A metal surface is illuminated by a light of given intensity and frequency to cause photoemission. If the intensity of illumination is reduced to one-fourth of its original value, then the maximum kinetic energy of the emitted photoelectrons would become
Options:
Answer:
D
Solution:
The maximum KE of the emitted photoelectrons is independent of the intensity of the incident light but depends upon the frequency of the incident light
