1.
Below the threshold frequency, increasing the intensity of light causes
no emission of electrons
electrons with more energy
electrons after a delay
a larger stopping potential
2.
The maximum kinetic energy of photoelectrons depends on
the intensity of the light
the time of exposure
the area illuminated
the frequency of the light
3.
If the intensity of light increases, with the same frequency above threshold, the photocurrent
decreases
increases
stays the same
becomes zero
4.
The stopping potential for a certain light is 2.5 V. The maximum kinetic energy is
2.5 J
5.0 eV
0.4 eV
2.5 eV
5.
Which observation does the wave theory fail to explain?
Photoelectrons are emitted with no measurable delay
Photocurrent increases with intensity
Metals contain free electrons
Metals conduct
6.
On a graph of photocurrent against voltage, doubling the intensity at constant frequency
doubles Vs
doubles the saturation current and leaves Vs unchanged
leaves both unchanged
halves the saturation current
