Assertion (A): In photo electric effect, photo electrons come out from inner orbits of atom.
Reason (R): Free electrons of the metal can not absorb energy of a photon.
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) Both (A) and (R) are false
Solution:
Assertion (A) is false: Photoelectrons are ejected from the surface of the metal, not inner orbits. Reason (R) is false: Free electrons absorb photon energy to be ejected. Both statements are false.
