Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
Which observation about the photoelectric effect supports the particle model of light?
Light undergoes diffraction
Electrons are emitted with no delay even for very dim light above threshold
Light can be polarised
Light shows interference fringes
2.
A photon has frequency 8.0 × 1014 Hz. What is its energy? (h = 6.63 × 10−34 J s)
1.2 × 10−48 J
8.3 × 10−20 J
5.3 × 10−48 J
5.3 × 10−19 J
3.
A graph of maximum kinetic energy of photoelectrons against light frequency is plotted. What does the gradient represent?
Planck constant
Threshold frequency
Work function
Intensity of the light
4.
The intensity of light on a metal is doubled while its frequency (above threshold) stays the same. What happens?
Maximum KE doubles
Both stay the same
Number of electrons per second doubles, maximum KE unchanged
Threshold frequency doubles
5.
Electrons passing through thin graphite produce rings on a screen. This shows that electrons
have charge
have mass
travel in straight lines
can show wave behaviour
6.
The accelerating voltage in an electron diffraction tube is increased. The rings
become smaller in radius
move outwards
disappear
stay the same
