The following observations are made about the photoelectric effect :
1. No electrons are emitted below the threshold frequency
2. Above the threshold frequency, the energy of the emitted electrons
depends only on the frequency of light
3.
Increasing the intensity of the light increases the number of emitted
electrons
Which, if any, of these observations can be explained by a wave theory of
light?
A
B
C
D
All of them
1 and 2 only
2 and 3 only
None of them
When the photoelectric effect experiments were performed, one effect was inconsistent with classical physics. What was it?
O A. The kinetic energy of the ejected electrons increased as the wavelength of light decreased.
O B. The kinetic energy of the ejected electrons increased as the frequency of light increased.
O C. The fact that light could free electrons from the surface of a metal.
O D. The kinetic energy of the ejected electrons did not vary with light intensity.
a) Draw a graph that shows the relationship between the frequency of the incident radiation
and the maximum kinetic energy of the electrons emitted from the photoelectric surface.
