Assertion (A): In the process of photo electric emission, all the emitted photoelectrons have same KE.
Reason (R): According to Einstein's photo electric equation \(KE= h\nu - \phi\).
(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: Kinetic energy of emitted photoelectrons varies from zero to maximum. Reason (R) is false: Einstein's equation is \(KE_{max}= h\nu - \phi\). Both statements are false.
