MCQ
With the decrease in the wave length of the incident radiation the velocity of the photoelectrons emitted from a given metal
  • A
    Remains same
  • B
    Increases
  • C
    Decreases
  • D
    Increases first and then decreases

Answer

  1. Increases

Explanation:

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