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 KE of emitted photoelectrons will become
A
(1/16)th of original value
B
Unchanged
C
Twice the original value
D
Four times the original value
Answer
Unchanged
Explanation
Solution
Maximum K.E. depends on the frequency of incident radiation, not on intensity
