UW UI retraction of light.
When a ray of light travelling in air enters obliquely into a glass
slab, it is observed that the light ray emerges parallel to the incident
ray but it is shifted sideways slightly. Draw a labelled ray diagram
to illustrate it.

Explanation:
thethe when the light moves from rarer to denser medium it bends towards normal it moves from denser to rarer medium it moves away from the normal so that when that light travels from air to glass crack the class 10 1.17 refractive index but I have three 0.33 refractive index so that it bends towards normal
