Hi Anton, good catch! IB Physics; Electricity and Magnetism notes 5.1 Electric Fields. Although the temperature of the CMB is almost completely uniform at 2.7K, there are very tiny variations, or anisotropies, in the temperature on the order of 10^-5K. Using the inverse square law, they can compute the distance to the supernova and thus to the supernova’s home galaxy. If there is not enough matter, the universe will keep expanding forever. Shall be updated regularly as the topics are covered. Hi Andrew, glad you’ve found the website helpful. Thus far, there have been 4 gamma particles created with 800,000 photons of light. This page contains fully editable PowerPoint slideshows for the current International Baccalaureate (IB) course in Physics. ... IDOCPUB. does it have all the things required to answer all questions? For maths, I suggest you work through past paper problems. 3 1 customer reviews 1 customer reviews I used your site to review my exam, and it is very good. • More than 50 questions for the core and HL extension with answers to test your understanding. Binary star: Two stars orbiting a common center. 5.2 Heating Effect of Electric Currents. Visit the post for more. Such a universe is “open”‘. The collapse of an interstellar cloud may begin if M>Mj where Mj is the Jeans criterion. This is really helpful. Find more resources made by Save My Exams today! It is to be noted that the Hubble “constant'” is not really a constant – it is different at different cosmological times. 🙂. Each positron is annihilated to create 2 gamma particles which are in turn absorbed and re-emitted as 200,000 photons of light per gamma particle. Here, High school or IB Students will get all the guidance, Notes and the Past papers of IB Physics, that will help you to understand about the level of this test and to achieve High score in Exam. Here's your secret weapon to ace your exams! The app is made mostly for IB Physics HL/SL students since these are the notes I made when doing my own revision. Hi Shruti, glad you’ve found it helpful! The concept of isotropy is supported by the fact that galaxies do not bunch up in any direction in the sky and by the fact that we observe the same Hubble relation in different directions in the sky. Space curves away from itself and time has no end. For systematic error’s explanation: “*Biased* in the same direction, the results are *always too large or too small*.” The surprising thing as there is very little visible matter far beyond the center of the galaxy. These notes are ideal preparation for unit tests as well as the final IB Exams. LET'S CONTRIBUTE. The anisotropies appear on the map as cooler blue and warmer red patches. Roughly 80 percent of the mass of the universe is made up of material that scientists cannot directly observe. Email. This would only be possible if the universe contained enough energy to overcome gravity – dark energy. I got a 7 fortunately. In other words, the halo of our galaxy is filled with a mysterious matter of unknown composition and type known as dark matter. The rotation curve of the galaxy indicates a great deal of mass but these masses cannot be observed. When the star is expanding, it rises in temperature and therefore rises in pressure. IB-PHYSICS. To be clear znotes.org is a non profit organization and you will be listed as a contributor on our website in exchange. Glad you found the notes helpful – ah yes, I fixed it, thanks for pointing it out! After the Big Bang, the universe began expanding outwards. What makes these notes unique? Search for: Close Menu.

Hi Andrew, thanks for pointing out. By the time the light reaches us, 14 billion years later, we observe it as low-energy microwaves at a frigid 2.7K. Great website. Hi Athul, I might know a site that may be helpful for Physics. There are two aspects of the cosmological principle: How do we measure the amount of mass in the universe? University Physics Revision Notes; All wiki articles on: Physics revision notes. Reason. The cluster has a much less well-defined overall shape. Two helium atoms fuse to create a heavy helium atom. (F=ma)”. The link doesn’t seem to be working. This is almost like a lifesaver.

For rectifications reach out to the subject lead. 3. The hydrogen around the core burns more fiercely and causes the outer part of the star to expand and cool down. The brightest star in the sky is known as Sirius and has a parallax angle of 0.379 arc seconds, apparent brightness of 1.2 × 10-7 W m-2, and a max wavelength of 292 nm. Hey David, my exam is in two days, and I was stressing out crazy, but then I found your website. The top shows the evolution of a Type Ia supernova while the bottom shows the evolution of a Type II supernova. I actually take notes from your notes on this site, even. If the region is truly representative, then the total mass of the universe=(the density)*(the total volume of the universe).

Type Ia supernovae occur in a binary system — two stars orbiting one another. The following 23 pages are in this category, out of 23 total. Thanks for reading. Which of these classes you took ? It should be corrected now, thanks. However, I managed to save some Powerpoints notable to this community and share it with you guys. As the universe expanded, the light was stretched into longer and less energetic wavelengths. Hi Dad(? I believe all the data I used for the IA are on the PDF document. If further fusion takes place, the star becomes a red giant. Our study guides, notes, and practice tests are constantly updated. Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. ​Topic 1: Measurement and uncertainties​, Topic 7: Atomic, nuclear and particle physics, Topic 12: Quantum and nuclear physics (HL), https://en.wikibooks.org/wiki/IB_Physics/Astrophysics_SL#F.1_Introduction_to_the_Universe, http://sciencevault.net/ibphysics/astrophysics/astrophysicsindex.html, http://study.com/academy/lesson/the-different-types-of-supernovae.html, http://hubblesite.org/hubble_discoveries/dark_energy/de-type_ia_supernovae.php, http://www.universeadventure.org/big_bang/cmb-origins.htm. D.1.2.17 The diagrams represent three positions, X, Y and Z, of a spectroscopic binary star system which contains stars A and B. Hey man! Most stars that are eight or more times the mass of our sun die as a Type II Supernova. There are three basic stages of the proton-proton cycle: Clouds of hydrogen and helium form into main sequence stars, where nuclear fusion takes place, fusing hydrogen to form helium. After doing so, your resources will be added to the post and to the main Google Drive link along with your credits (Example: Math HL notes by /u/(whatever your username is). Hi Mohamad, I don’t have pre-IB materials unfortunately since these are simply notes I wrote during my IB revision. This is a collection of IB Physics notes. 2. Some of these might be obvious things, but I think it’d be useful to have them nonetheless! Found a minor formatting error: under ”Graphs describing motion” in Topic 2, the graph header isn’t made to be in the same format as the rest of the graph headers. White dwarf stars are one of the densest forms of matter, second only to neutron stars and black holes. I’ve corrected that part to make it more clear – thanks for pointing it out! This means you see no difference in the structure of the universe as you look in different directions. Hi Zubair, I’d be happy for you to use my notes, as long as a clear disclaimer and contribution is noted. I believe it is meant to be in header 2 format, but it is just regular text sizing at the moment.

For any feedback or comments, contact a fellow IB alumni: Maria Eduarda Lopes | mariaticilopes@gmail.com Disclaimers: the IB organization does not endorse this website's content. An explanation of how the stellar parallax method can be used to determine the distance to a star. Hi G, I guess you can use the notes both for studying and review. 5. The white dwarf will begin to pull material off its companion star, adding that matter to itself. Example. Ib Notes: Sl Physics Definitions + Astrophysics. This means that the mass of the galaxy increases with increasing distance from the center (radius). Shall be updated regularly as the topics are covered. In Astrophysics Part D.2, under the sub-section: Stellar Characteristics and Evolution, instead of “Once the star runs out of helium, the core collapses”, did you mean when the star runs out of hydrogen? Below are some amazing resources to prepare for both SL and HL Physics. Olbers’ paradox Red shift Expanding universe The … Hi Zaid, I’d recommend thoroughly studying the exam materials before jumping to past papers.
