A LEVEL PHYSICS PAPER 2 EXAM WITH CORRECT 65+ QUESTIONS WITH CORRECTRY ANALYZED ANSWERS (ACTUAL EXAM) ALREADY GRADED A+ LATEST 2024 Difference between Compton scattering to simple scattering - ANSWERS -• X-ray photon imparts some of its energy to the orbital electron Because of this exchange of energy -The X -ray is deflected from its initial path -The X -ray's wavelengthincreases, as its energy decreases - The electron involved is ejected from the atom involved in the interaction What happens to the electron and x ray - ANSWERS -collide and deflected in different directions due to conservation of momentum Pair production occurs when - ANSWERS -A high energy X -ray photon passes close to the nucleus of an atom causing the production of an electron -positron pair Wavespeed - ANSWERS -distribution travelled by a wave per unit time Frequency - ANSWERS -number of waves that pass through a point per second what are p waves and s waves - ANSWERS -p waves are longitudinal s waves are transverse Displacement - ANSWERS -distance from the equilibrium position in a particular direction Period - ANSWERS -time taken for a full oscillation of one wavelength time pass a given point Wavelength - ANSWER S-distance between 2 adjacent points on a wave Amplitude - ANSWERS -maximum displacement of a wave from its equilibrium point Phase difference - ANSWERS -difference in displacement of particles along a wave. What are the axes on an oscilloscope - ANSWERS -horizontal time vertical voltage/amplitude Refraction - ANSWERS -when a wave bends at a boundary between two materials due to different in density causing it slow down or speed up. What direction will refraction move towards - ANSWERS -from air to a denser medium it will move towards the normal. From a denser medium to air it will refract away What is the incidence - ANSWERS -light that is pointing towards and striking a surface What is the refracted ray - ANSWERS -light that has entered a second medium Refraction equation - ANSWERS -n=c/v n is the refraction index c is speed of light in a vacuum and v is speed of light in the medium. Refraction index equation with angles - ANSWERS -sini/sinr = n, sini is the sin angle of incidence, sinr angle or refraction and n is refraction index. This is snells law Young double slits equation - λ = ax/D what are they - ANSWERS -λ wave length, a slit separation in front of the laser, x is distance between fringes(fringes the pieces of light on the screen), D is the distance between slit and screen) Superposition - ANSWERS -When two or more progressive waves meet and overlap they superpose, producing a single wave. Principle of superposition - ANSWERS -when two waves meet at a point, the resultant displacement of the wave at that point is equal to the sun of displacement s.
