Photoelectric emission occurs only when the incident light has more than a certain minimum

A

wavelength

B

Intensity

C

frequency

D

power

Text Solution

Verified by Experts

The correct Answer is:
C
By the concept of threshold minimum frequency needed for photoelectric emission.
`(1)/(2) mv^(2) = h ( v - v_(0))`
`v ge v_(0)`
