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

A

speed of wave increases

B

wavelength of wave decreases

C

amplitude of wave increases

D

there is no change in phase angle

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
`A_t = ((2v_2)/(v_1+v_2))A_i`
If `v_1 gt v_2` , `A_t gt A_i`.

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

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.

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 (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.

When light travels from a denser medium to a rarer medium, what is the effect on its speed? A) Increases B) No change C) Decreases D) Decreases and then increases

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

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.
