307374 Assertion :
Threshold frequency is a characteristic for a metal.
Reason :
Threshold frequency is the maximum frequency required for the ejection of electron from the metal surface.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.

307375 In photoelectric effect, the photo current

1 Increases with increase of frequency of incident photon
2 Decreases with increase of frequency of incident photon
3 Does not depend on the frequency of photon but depends only on the intensity of incident light
4 Depends both on intensity and frequency of the incident photon

307376 Which statement regarding the photoelectric effect is false?

1 The current does not depend on the colour of the light as long as the wavelength is short enough.
2 Electrons can be ejected only if the light is of sufficiently short wavelength.
3 The wavelength limit sufficient for the ejection of electrons is the same for different metals.
4 The current increases with increasing intensity of the light.
