CUET Physics
In Compton scattering, the Compton wavelength shift is maximum when the scattering angle θ is:
A 0 degrees
B 45 degrees
C 90 degrees
D 180 degrees
CUET Physics
The stopping potential in the photoelectric effect depends on:
A the intensity of incident light only
B the work function of metal only
C the frequency of incident light and work function of metal
D the area of the metal surface
CUET Physics
In the photoelectric effect, no electrons are emitted if the incident light frequency is below the threshold frequency ν₀ because:
A the light intensity is too low
B the photons do not have enough energy to overcome the work function
C the light wave amplitude is insufficient
D the metal surface is too smooth
CUET Physics
In the photoelectric effect, the saturation current is directly proportional to:
A the frequency of incident light
B the work function of the metal
C the intensity of incident light
D the stopping potential
CUET Physics
In the photoelectric effect, increasing the intensity of incident light (above threshold frequency) while keeping frequency constant causes the stopping potential to:
A increase
B decrease
C remain the same
D become zero
CUET Physics
The energy of a photon of frequency ν is (where h = Planck's constant):
A E = hν²
B E = hν
C E = h/ν
D E = ν/h
CUET Physics
In the photoelectric effect, the maximum kinetic energy of emitted photoelectrons depends on:
A the intensity of incident light
B the frequency of incident light
C the area of the metal surface
D the shape of the metal surface
CUET Physics
