Photoelectric Effect

The particle ejected from the metal is called a

• photoneutron

• photoproton

• photoelectron

• photomeson

When I increase the intensity of the incident light,

• the frequency of light increases

• the wavelength of light increases

• the number of incident photons increases

• the energy of each incident photon increases

If I increase the frequency of light,

• the energy of each photon decreases

• the energy of each photon increases

• the energy of each photon remains the same

If I increase the wavelength of light,

• the energy of each photon increases

• the energy of each photon decreases

• the energy of each photon remains the same

If I increase frequency of light,

• the energy of each photoelectron increases

• the energy of each photoelectron decreases

• the energy of each photoelectron remains the same

If I increase the wavelength of light,

• the energy of each photoelectron increases

• the energy of each photoelectron decreases

• the energy of each photoelectron remains the same

The photocurrent depends on:

• the energy of the ejected photoelectron

• the number of photoelectrons ejected

• the rate of photoelectrons ejected

• the energy of the photon

If I decrease the wavelength of light,

• the rate of photoelectrons ejected increases

• the rate of photoelectrons ejected decreases

• the rate of photoelectrons ejected remains the same

If I increase the frequency of light,

• the rate of photoelectrons ejected increases

• the rate of photoelectrons ejected decreases

• the rate of photoelectrons ejected remains the same

If I decrease the frequency of the incident light,

• the magnitude of the stopping voltage increases

• the magnitude of the stopping voltage decreases

• the magnitude of the stopping voltage remains the same
