Assertion : A photon has no rest mass, yet it carries definite momentum. Reason : Momentum of photon is due to its energy and hence its equivalent mass.
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.
Explanation:
for photon. But We also know So correct option is (1).

Assertion : An electron microscope is based on de Broglie hypothesis. Reason : A beam of electrons behaves as a wave which can be converged by electric and magnetic lenses.
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.
Explanation:
Electron microscopes, based on in de Broglie's wavelength concept, utilize short electron wavelengths for high-resolution imaging. Their superiority over optical microscopes lies in the ability to resolve atomic and molecular details. So correct option is (1).
