Question

By how much would the stopping potential for a given photosensitive surface go up if the frequency of the incident radiations were to be increased from 4 x 1015 Hz to 8 x 1015 Hz? Given h = 6.4 x 10-34 J-s, e = 1.6 x 10-19 C and c = 3 x 108 ms-1

Answer 1

I actually happen to have found out the rise in energy. I just don't know how to find the stopping potential with that

Answer 2

@Mashy Can ya help dude :3 ?

@ganeshie8 ?

Answer 4

@Saeeddiscover can you help please?

Answer 5

that is not 1015, its 10^-15
