Aphoto cell emits electrons when yellow light falls on it. which of the following statements is correct if a light of frequency that is two times yellow light falls on it?

Velocity of the emitted electrons increases

Explanation:

Velocity is directly proportional to frequency and this can be seen from the equation

v=fλ

Hence, if the frequency increases, the velocity is bound to also increase. Thus  an increase in frequency as stated in the questions would definitely result to an increase in the velocity of the emitted electrons as seen from the equation above.
