Question

Draw a labelled ray diagram to show the path of a ray of light
incident obliquely on one face of a glass slab.​

Answer 1

Answer:

for more clarity check ur refresher of physics

Answer 2

We know that,

In the diagram ,

i is the incidence ray, r is the refracted ray and e is the emergent ray.

We need to draw a labelled ray diagram

Which show the path of a ray of light incident obliquely on one face of a glass slab is,

The incident angle , reflected angle, emergent angle and lateral displacement clearly maintain in the diagram.

Incidence angle :

The angle between incidence ray and normal line is called incident angle.

Refracted angle :

The angle between refracted ray and normal line is called refracted angle.

Emergence angle :

The ray which comes out of a refracting medium it is called emergent ray.

The angle between emergent ray and normal line is called emergence angle.

Hence, This is required answer.
