Assertion When a wave travels from a denser to a rarer medium, its amplitude increases.
Reason In a rarer medium, speed of wave is more

A

If both Assertion and Reason are true and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are true but Reason is not correct explanation of Assertion.

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
(a) `A_(t)=((2v_(2))/((v_(1)+v_(2))A_(i)`
If `v_(2)htv_(b)` then `A_(t)gtA_(i)`

When a wave travels from a denser to rarer medium, then

Assertion: When a wave travels from a denser medium to rarer medium, then ampltitude of oscillation increases. Reason: In denser medium, speed of wave is less compared to a rarer medium.

When light passes from a denser medium to a rarer medium

Assertion (A): When a light wave travels from rarer to denser medium, its speed decreases. Due to this reduction of speed the energy carried by the light wave reduces. Reason (R): Energy of wave is proportional to the frequency.

A wave travels from a denser medium to rarer medium, then match the following two columns

Answer the following, giving reason:- (a) When light travels from a denser to a rarer medium, the speed increases. Does it mean that there is an increase in the energy carried by the waves ? (b) The Sun appears reddish at sunset and sunrise.

Assertion: When a light wave travels from a rarer to a denser medium, it loses speed. The reduction in speed imply a reduction in energy carried by the light wave. Reason: The energy of a wave is proportional to velocity of wave.

A wave is transmitted from denser to a rarer medium. Then match the following.
