h = plank's constant. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. Mr Brandon is an extremely passionate and cheerful teacher, who makes learning fun and enjoyable with his optimism. Why are fireworks coloured, how can we tell what elements are in stars just from the light we see? This video explains why physics is all about sunshine and rainbows. A series of workbooks with questions for every day of your A Level course. This dual behaviour of displaying both particle and wave nature is known as the dual behaviour of matter, and for every particle, the particle nature comes from its mass, and the wave nature comes from its matter-wave defined by the De-Broglie relationship, which is given by, //. Hence, there was a need for a new theory that could explain the behaviour of atomic and sub-atomic particles. Different atoms of the same element are identical. Photons exhibit wave properties under refraction or interference. Share. The energy of a photon can be worked out by multiplying the frequency by the Planck's Constant which was created by one of the pioneers in Quantum Physics. Theoretical Physics, Philosophy of Physics and Astronomy - Umar Sohail Qureshi; Design and Technology - Abdullah Soomro . Part of. 6.63 x 10^-34 J/s or 4.14 x 10^-15 eV/s. This video shows why this can only explained by the interaction of individual packets of energy. When quantum mechanics is applied to macroscopic objects (for which wave-like properties are insignificant) the results are the same as those from classical mechanics. PREVIOUS POST Notes - Phase of Matter . Circuits Electromagnetism Electromagnetic Induction Alternating Current The A Level Physics content here is equivalent to the Physics required for Advanced Placement. The position and momentum of a sub-atomic particle can be calculated simultaneously with some degree of inaccuracy. Blackbody radiation. Electromagnetic Spectrum. Find a one-to-one tutor on our new Tuition Platform . It results in us only being able to predict probabilities, while one classically can make deterministic predictions. New spec A2 Past Papers. Package includes; A complete 44-page presentation resource-pack explaining in detail the whole chapter. 1 file(s) 819.93 KB. Mark Scheme . im thankful for his time and, effort to help me improve. If waves can sometimes exhibit particle like properties, does that mean that electrons that we have always through of as particles also behave as waves? A-Level Physics Revision section of StudyWise. Cambridge International AS and A Level Physics is ideal for learners who want to study physics or a wide variety of related subjects at university or to follow a career in science. The light is completely absorbed by the surface.Calculate the number of photons incident on the surface in 2.0 s. Step 1: Write down the known quantities, Step 2: Write the equations for wave speed and photon energy, Step 3: Calculate the energy of one photon, Step 4: Calculate the number of photons hitting the surface every second, Step 5: Calculate the number of photons that hit the surface in 2 s. The values of Plancks constant and the speed of light will always be given to you in an exam, however, it helps to memorise them to speed up calculation questions! This course will serve as a comprehensive introduction to the foundations of quantum mechanics, from the modern point of view of 21st century theoretical physics. Something to do with photons and electricity. 150290-learner-Learner Guide for AS and A Level Physics : Download. 1. All exam boards Classical Physics was not successful in explaining the dual behaviour of a matter. THE BOHR ATOM: Bohr proposed a revolutionary model: An atom with discrete (Quantum) states - an ad hoc model Bohr's atom model achieved three important results: 1. CIE A Level; Physics 9702; Smart Notes Online is an educational platform that makes studying Smart, Easier, Better and Less-time consuming. A rather long video covering the section on Quantum Physics on the OCR Physics A specification, however applicable to all exam boards. 140. Description. Old spec A2 Past Papers. These papers contain both long questions and multiple choice questions. Quantum mechanics is the branch of physics that deals with the behavior of matter and light on a subatomic and atomic level. Measurements and their errors. Paper 2 consists of the other three topics (not the optional topic). The syllabus includes the main theoretical concepts which are fundamental to the subject, a section on some current applications of physics, and a strong emphasis on advanced practical skills. This video shows how we can use the particle model, with individual corpuscles of energy, to explain certain properties of EM radiation. Furthermore he is able to help students understand a topic better through practice and consulting. Resources include A-Level Physics Revision Notes, A-Level Physics Help Forums (General Revision + Edexcel, AQA, OCR & WJEC), Exam Specs, Exam Papers, Physics Revision Guides (A Level) & More. A Level Physics Syllabus : Download. Quantum mechanics is required to analyze the behavior of molecules, atoms, and nuclei. Quantumphysics Notes - Faculties | About Macquarie University Quantum physics tries to explain the properties of matter and energy at the atomic and subatomic levels. In contrast, on the other hand, the atomic level particles have very little mass, and hence both particle and wave nature is prevalent in them. Paper 1 is all the Year 12 work AND the periodic motion topic. 3. A pre-quantum quantum history: spectroscopy, the Bohr model and the photon. A full set of A level physics notes free to download.

Step 5: Calculate the number of photons that hit the surface in 2 s. (8.9 1015) 2 = 1.8 1016. Newtons laws of motion can explain the behaviour of macroscopic objects or objects that are at a scale of human interaction and experience, even including astronomical objects. Katie has always been passionate about the sciences, and completed a degree in Astrophysics at Sheffield University. KS3 .
