Directions : In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as :
(a) If both assertion and reason are true and reason is the correct explanation of assertion.
\( \mathrm{P} \)
(b) If both assertion and reason are true but reason is not the correct explanation of assertion.
(c) If assertion is true but reason is false.
W
(d) If both assertion and reason are false.
Assertion : When a plane wave passes through a thin prism, the emerging wavefront gets tilted.
Reason : Speed of light is less in glass than in air.
