In a photoelectric experiment ,the maximum velocity of photoelectrons emitted

A

Depends on intensity of incident radiation

B

Does not depend on the cathod material

C

Depends on frequency of incident radiation

D

Does not depend on wavelength of the incident radiation

Text Solution

Verified by Experts

The correct Answer is:
C

Einsteins photoelectric equation is given by,
`(1)/(2)mv_(max)^(2)=hv-hv_(o)`
This euation clearly states that the maximum velociity of photo electrons depends on frequency of incident radiation
