Question

6. In photoelectric effect which of the following will increase the kinetic energy of an
ejected electron.......
a) increasing the wavelength of the light striking the surface.
b) increasing the frequency of light striking the surface.
c) increasing the intensity of light striking the surface.​

Answer 1

Answer:

Answer is option b

Explanation:

The kinetic energy of emitted photoelectrons should increase with the light amplitude. The rate of electron emission, which is proportional to the measured electric current, should increase as the light frequency is increased.

Answer 2

Answer:

a.as a wavelength of the light striking the surface when light increases, the skin of the depth of the metal increases. so the light can increases the more electrons.

b. if the increasing the frequency of light striking the surface then the number of photons restricting the surface at per second then increase in the same ratio.

c.striking the surface because of the photons.
