what happens when a Ray of light is incident normally on a glass slab ? why ?
Answers
Answer:
If a ray of light is incident normally, angle of incidence will be zero as all angles are measured from normal. so, if a ray of light is incident normally on the glass slab, then angle of refraction will be 00 .
When a Ray of light is incident normally on a glass slab because the angle of incidence and the angle of refraction is zero.
Explanation:
As light rays moving through the air penetrate the glass slab, they become refracted and bent toward the normal. So the direction of the refracted ray shifts again as it falls out of the slab of glass into the air. Since the light ray that I know travels from the denser medium to the rarer medium, it bends away from the normal. For this scenario, the incident ray and the emerging ray are opposite to each other. There is no bending of the ray of light when entering or coming out of the glass slab. In this case, the angle of incidence and the angle of refraction is zero.
