Question

photoelectrons are only emitted if the wavelength of the light is shorter than some maximum value number method how intense the light is show the colour wavelength is critical true or false​

Answer 1

Answer:

Correct option is

B

Maximum velocity of photoelectrons depends only on frequency of the incident light.

C

Photoelectric current increases with increase in intensity of incident light (keeping frequency fixed).

The velocity of the photoelectron is directly proportional to the frequency of light while the current is directly proportional to the intensity of the light incident on the surface. The only important thing is that the light should have a frequency greater than the threshold frequency.

Answer 2

Answer:

Explanation:

It is a false statement

Incident frequency should begreater than or equal to threshold frequency
