When a light of wavelength $400 \mathrm{nm}$ is incident on the cathode of a photocell, the stopping potential recorded is $6\mathrm{V}$. If the wavelength of the incident light is increased to $600 \mathrm{nm},$ then the new stopping potential is

The photoelectric effect proves that

A monochromatic light of frequency $v$ is incident on emitter having threshold frequency $v_0$. The kinetic energy of ejected electron will be

As the intensity of incident light increases
