What happens when incident ray falls on the surface of a glass slab? what is angle of incident and angle of refraction? Draw the diagram in this case?

When an incident ray of light is incident on the glass slab then the light ray undergoes refraction.
The following diagram represents the refraction of light through glass slab: -
Angle of incidence : - Angle between the incident ray and normal is called angle of incidence.
It is denoted by letter 'i'
Angle of refraction: - Angle between the refracted ray and normal is called angle of refraction.
It is denoted by letter 'r'
If the light ray is incident on the glass slab perpendicularly then there is no refraction.
In this case the diagram is as follows: -

- what is total internal reflection? Under what conditions does it take place.
- Question: A ray of light travelling in air falls on the surface of a transparent glass slab at an angle of 60° with the normal to the surface. Find the angle made by the refracted ray with the normal within the glass slab. Refractive index of the glass slab is .
- define the term dispersion of white light. name the colour of light which bends the most.
- 1.A student observes below phenomenon in the lab as a white light passes through a prism. Among many other colors, he observed the position of two colors: red and violet. (A)What is the phenomenon called? (B)What is the reason for violet light to bent more than the red light? (Ref to: image 1) 2 points Add File
- explain. why angle of incidence= Angle of emergence ?
- Why light rays do not bend or refract when they meet the glass slab perpendicularly? (Pls ans theoratically and dont say it is bcs i is 0)
- please explain refraction through glass slab
- explain why pool of water apper to be less dept then its actually is with diagram
- what happens when a red light passes through a prism?
