When orange light falls on a photo sensitive surfaces the photo current begins to flow. The velocity of emitted electrons will be more when surface is hit by

Intensity of light incident on a photo sensitive surface is doubled. Then

Insentity of light incident on a photo sensitive surface is doubled. Then

Intensity of light incident on a photo sensitive surface is doubled. Then

When light falls on a photosensitive surface, electrons are emitted from the surface. The kinetic energy of these electrons does not depend on the:

An electromagnetic radiation of frequency 3xx10^(15) cycles per second falls on a photo electric surface whose work functions is 4.0eV. Find out the maximum velocity of the photo electrons emitted by the surface.

A metal surface ejects electrons when hit by green light but none when hit by yellow light. The electrons will be ejected when the surface is hit by
