Question

With the decrease in the wave length of the incident radiation the velocity of the photoelectrons emitted from a given metal
  1. Remains same
  2. Decreases
  3. Increases first and then decreases
  4. Increases

A
Remains same
B
Increases
C
Decreases
D
Increases first and then decreases
Solution
Verified by Toppr

As wavelength decrease , frequency increases and hence K.E of photoelectrons increases , thereby increasing the velocity.
