The photoelectric work function for a metal surface is 2.4eV.If a light of wavelength 5000Ais incident on the surface of the metal, find the threshold frequency and incident frequency. Will there be emission of photoelectrons or not?

When a ray of light is incident normally on a surface, then

When a ray of light is incident normally on a surface, then

When a ray of light is incident normally on a surface, then

Photoelectric emission occurs only when the incident light has more than a certain minimum

Photoelectric emission occurs only when the incident light has more than a certain minimum

Photoelectric emission occurs only when the incident light has more than a certain minimum

Threshold wavelength for photoelectric emission from a metal surface is 3800Å , Utraviolet light of wave-length 2600Å is incident on the metal surface. Find the work function of the metal and

Blue light can cause photoelectric emission from a metal, but yellow light cannot. If red light is incident on the metal, then
