According to photon picture of electromagnetic radiation, which of the following statements is incorrect?
Answer & explanation
Correct answer: option 4
The correct answer is Option 4: In a photon-electron collision, the total energy and total momentum are not conserved.
In all interactions (including photon-electron collisions like the Compton effect), both energy and momentum are always conserved.
Features of the photons:
(i) Photon are particles of light having energy E=hv and momentum p=h/λ, where h is Planck constant.
(ii) Photons travel with the speed of light in vacuum, independent of the frame of reference.
(iii) Intensity of light depends on the number of photons crossing unit area in a unit time.
(iv)Photons are electrically neutral.
