Question

Direction: In the given question a statement of assertion and a corresponding statement of reason is given \ Assertion: When a light wave travels from a rarer to denser medium, its speed decreases. The decrease in speed imply a reduction in energy carried by the light wave. \ Reason: The energy of a wave is inversely proportional to velocity of wave.\ Choose the correct alternative from given below.

Speed decreases but energy remains constant since it depends on frequency, not speed. Both assertion and reason are false.
