Why is it the refracted ray bends towards the normal, and while entering from denser to rarer it bends away from the normal.

Answer the following questions The observations made by swarali while doing the experiment are given below. Based on these write answers to the questions: Swarali found that the light ray trvelling from the denser medium to a rarer medium goes away from the normal. If the angle of incidence (i) is raised by Swarali, the angle of refraction (r) went on increasing . However after certain value of the angle of incidence. the light ray is seen to return back into the denser medium What is the process of reflection of incident ray into a denser medium called ?

When light ray travels from denser medium to rarer, then it

State whether the following statements are True or False : When a light ray travels obliquely from an optically rarer medium to an optically denser medium, it bends away from the normal.

Read the statements given below and identify the concepts explained in them. When Reema observes a light ray coming from medium 2 into medium 1, she sees that the ray bends away from the normal while entering the medium 1. Which medium in this case is optically rarer?

Explain reflection of longitudinal wave travelling from denser to rarer medium.

Explain reflection of transverse wave whena wave pulse is sent from a denser to a rarer medium.

The refractive index of water relative to air is 5/3. A ray of light passing from water into air is incident at the interface at an angle of 32^(@) with the normal. What angle does the refreacted ray make with the normal?
