Question

Assertion (A): When rays of white light pass through a prism, on emerging they give spectrum of seven colours.

Reason (R): It is due to the scattering of light that red light bends minimum and violet light bends the maximum.

पर्याय

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

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

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

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

Answer 1

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

Explanation:

White light splits into seven colours when passing through a prism due to dispersion of light, so the assertion is true. However, the Reason is incorrect because the bending of colours is due to refraction (different refractive indices), not scattering.
