Question

Assertion (A): If accelerated electrons are passed through a narrow slit, a diffraction pattern is observed.

Reason (R): Electrons behave as both particles and waves.

Options

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (А).

• Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (А).

• Assertion (A) is true, but Reason (R) is false.

• Both Assertion (A) and Reason (R) are false.

Answer 1

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (А).

Explanation:

The assertion is true as electrons passing a narrow slit generate diffraction patterns, a characteristic of wave phenomena. The reason is true as electrons show wave-particle duality. Their wave characteristics, as explained by de Broglie wavelength, account for the observed diffraction. Thus, the reason correctly explains this assertion.
