Transcribed Image Text:7. Which of the following statements is true for
the experimental findings on photoelectric
effect?
Within the limits of experimental accuracy
there is not time interval between the
arrival of light at the metallic surface and
emission of photoelectrons.
A bright light yield the same number of
photoelectrons than a dim one at the
same frequency but the electron energies
are not the same.
Higher frequency of light yields more
photoelectrons at the same intensity of
light incident on the metal surface.
Both the intensity and frequency of light
do not affect the number of
photoelectrons produced at the metallic
surface as well as the energy of the
emerging photoelectrons.
Transcribed Image Text:8. The experiment that confirmed the existence
of de Broglie waves is the
Millikan-oil drop experiment.
Moessbauer Effect experiment.
Frank-Hertz experiment.
Davisson-Germer experiment.
