PHXII11:DUAL NATURE OF RADIATION AND MATTER

357790 Assertion :
The threshold frequency of photoelectric effect supports the particle nature of sunlight.
Reason :
If frequency of incident light is less than the threshold frequency, electrons are not emitted from 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.
PHXII11:DUAL NATURE OF RADIATION AND MATTER

357791 Assertion :
Photoelectric emission is an instantaneous process.
Reason :
There is no time lag between incidence of light and emission of photoelectron.

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 Both Assertion and Reason are incorrect.

PHXII11:DUAL NATURE OF RADIATION AND MATTER

357792 Statement A :
Though light of a single frequency (monochromatic) is incident on a metal, the energies of emmited photoelectrons are different.
Statement B :
The energy of electrons emitted from inside the metal surface is lost in collision with the other atoms in the metal.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
PHXII11:DUAL NATURE OF RADIATION AND MATTER

357793 When light of wavelength \(300\;nm\) falls on a photoelectric emitter, photoelectrons are liberated. For another emitter, light of wavelength \(600\;nm\) is sufficient for liberating photoelectrons. The ratio of the work function of the two emitters is

1 \(1: 2\)
2 \(2: 1\)
3 \(4: 1\)
4 \(1: 4\)
