Question

How does the light have to enter the glass?; (a) To produce a large amount of bending?; (b) For no refraction to happen?

Answer 1

Answer:

it is a phenomenal of light band rare medium to Denver medium

and this is also called low of daviation

Answer 2

Answer:

(a)If light enters any substance with a higher refractive index (such as from air into glass) it slows down. The light bends towards the normal line. ... As the light enters the water, it is refracted. Since thelight is passing from air (less dense) into water (more dense), it isbent towards the normal.

(b)when light rays is normal at the surface no refraction happens. 1) Iflight enters any substance with a higher refractive index (such as from air into glass) it slows down. The light bends towards the normal line
