Question

Assertion (A): At the boundary separating the two media, light suffers partial reflection and partial refraction.

Reason (R): The intensity of refracted light will be less than that of the incident light.

पर्याय

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

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

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

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

Answer 1

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

Explanation:

At the boundary, light splits into reflected and refracted parts. Because some light energy is reflected, the intensity of the refracted light is naturally less than the incident light. This energy split perfectly explains the process of partial reflection.
