Q. The retarding potential for having zero photo-electron current
Rajasthan PET
Rajasthan PET 2002
A
is proportional to the wavelength of incident light
B
increases uniformly with the increase in the wavelength of incident light
C
is proportional to the frequency of incident light
D
increases uniformly with the increase in the frequency of incident light wave
Solution:
Higher the frequency of incident light, higher will be the stopping potential. Thus, the value of electric current will become zero.
