The threshold frequency for a certain photosensitive metal is When it is illuminated by light of frequency ,the maximum velocity of photoelectrons is . What will be the maximum velocity of the photoelectrons when the same metal is illuminated by light of frequency ?
View answer and explanation
Correct option: B
Option B () is correct because the maximum velocity is proportional to the square root of the frequency difference from the threshold frequency.
