In a photoelectric emission process the maximum energy of the photo - electrons increase with increasing intensity of the incident light .

Text Solution

Verified by Experts

`(K.E.)_(max) = knu - k nu_(0) rArr (K.E.)_(max) prop nu`
That maximum kinetic energy is proportional to frequency and not intensity.
