PHXII11:DUAL NATURE OF RADIATION AND MATTER

357811 Assertion :
Some photographic plates are not affected by red light but are immediately blackened by white light.
Reason :
The wavelength of red light is less than the wavelength of many components of white light.

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

357812 Assertion :
Work function of metal is \(4.2\,eV\). Emission of electrons is possible if two photons each of energy \(2.5\,eV\) strike an electron of the metal.
Reason :
For photoelectric emission the energy of each photon should be greater than the work function of the metal.

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.
