Question
-According to the experiment concerned with the photoelectric effect, which of the following will increasethe kinetic energy of an electron ejected from a metal surface? Select all correct answers!
None of these.
Increasing the number of photons of light striking the surface.
Increasing the wavelength of the light striking the surface.
Increasing the frequency of the light striking the surface.
a)None of these.
b)Increasing the number of photons of light striking the surface.
c)Increasing the wavelength of the light striking the surface.
d)Increasing the frequency of the light striking the surface.
Explanation / Answer
KE = E - Eo
Eo is cut off energy and E is energy of photon
SO, to increase Kinetic energy , E must increase
E increases when frequency increases since E = h*f
Answer:
d Increasing the frequency of the light striking the surface.
