When a longitudinal wave travels from one medium to another, a compression is reflected as a rarefaction. What can you say about the medium ?

If a wave is going from one medium to another, then

If a wave is going from one medium to another, then

Ray of light bends as light travels from one medium to another.

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

A longitudinal wave travels from a rarer medium to a denser medium and gets reflected. Draw a diagram to explain the reflection

One of the angles forming a linear pair is a right angle. What can you say about its other angle?

When monochromatic light travels from one medium to another, its wavelength changes, but its frequency remains the same. Why ?

(A): If wave enters from one medium to another medium then sum of amplitudes of reflected wave and transmitted wave is equal to the amplitude of incident wave. (R): If wave enters from one medium to another medium energy is transmitted only.

Let the refractive index of a denser medium with respect to a rarer medium be n_(12) and its critical angle be theta_(c) . At an angle of incidence A when light is travelling from denser medium to rarer medium, a part of the light is reflected and the rest is refracted and the angle between reflected and refracted rays is 90^(@) , Angle A given by -
