Identify the correct statement regarding Einstein's photoelectic effect
(a)The number of electrons ejected depends on the wavelength of incident radiation.
(b)Electron ejection can occur at any wavelength of incident radiation.
(c)The number of electrons ejected at a given incident wavelength depends on the intensity of the radiation.
(d)The kinetic energy of the ejected electrons is independent of the wavelength of incident radiation.
Answer
Answer: C ✓ checked by 4AB · confidence high
Explanation
Above the threshold, the number of photoelectrons is proportional to light intensity; their kinetic energy depends on frequency (c).
