W. correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion \& Reason are False.
Assertion : A prism of refracting angle \( 60^{\circ} \) is made of a material of refractive index \( \sqrt{2} \) for a certain wavelength. As light of this wavelength passes through the prism, angle of minimum deviation is \( 30^{\circ} \).
Reason : At minimum deviation, angle of refraction of the first face is \( r_{1}=\frac{A}{2}=30^{\circ} \).
