(b)

To determine

The maximum kinetic energy of the ejected photoelectrons will most likely be reduced by a factor of 10 if the intensity of the incident light is reduced by a factor of 10 .

(c)

To determine

The maximum speed of the ejected photoelectrons will most likely be reduced by a factor of 10 if the intensity of the incident light is reduced by a factor of 10 .

(d)

To determine

The maximum speed of the ejected photoelectrons will most likely be reduced by a factor of 10 if the intensity of the incident light is reduced by a factor of 10 .

(e)

To determine

Blurred answer
Students have asked these similar questions
In the photoelectric effect (for a given target and a given frequency of the incident light), which of these quantities, if any, depend on the intensity of the incident light beam: (a) the maximum kinetic energy of the electrons, (b) the maximum photoelectric current, (c) the stopping potential, (d) the cutoff frequency?
The surface of a metal is illuminated alternately with photons of energies E1 = 4 eV and E2 = 2.5 eV respectively. The ratio of maximum speeds of the photoelectrons emitted in the two cases is 2. The work function of the metal in (eV) is
In the photoelectric effect, explain why the stopping potential depends on the frequency of the light but not on the intensity.
