1ans is only A. its from HC VERMA.............................plz help !!
i have got B to be incorrect.how A????
find the correct statements.
If Frequency and Intensity of a light source are doubled.Then
a)SAtURATioN photocurrent remains almost the same.
b)Maximum Kinetic Energy of photoelectrons are doubled.

1The saturation photocurrent is directly proportional to the intensity of the incident light ray , and independant of the frequency of the light ray . Interestingly , the maximum kinetic energy of photoelectrons is independant of the intensity of the incident ray , but directly proportional to the frequency of the light ray .
Based on these facts , we can conclude that " ( b ) " is the correct question .
49maximum KE=hν-hνo
on doubling ν
we dont double max.KE do we? :-/
1Yep , I got carried away owing to the fact that the set of questions must have a correct answer :)
However , you are absolutely correct Shubhomoy .
