Question

Why light rays travelling from a denser to a rarer medium,And show the diagram also.​

Answer 1

Answer:

Water is rarer than glass. Light travels from water to glass, i.e from a rarer medium to a denser medium.

The incident ray is AO

Angle of incidence is i.

Angle of refraction is r.

Explanation:

Diagram is in the image

Answer 2

Answer:

When light travels from a denser medium to a rarer medium, it bends away from the normal, as illustrated to the left.  This behavior follows from Snell's Law.  As you saw before, the larger angle must be in the medium having the lower index of refractionhen light travels from a denser medium to a rarer medium, it bends away from the normal, as illustrated to the left.  This behavior follows from Snell's Law.  As you saw before, the larger angle must be in the medium having the lower index of refraction.
