Applications Of Reflection Of Light

When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.

Sign Convention for Mirrors

A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.

Question

**IR-1** Fredy is lying on the bottom of the swimming pool looking up.
a) Draw a figure like the one below and show rays entering Fredy's eye coming:
1. straight down,
2. entering the water at an angle of 30° from the normal, and
3. entering the water at 89.999° from the normal.

[Diagram]
The diagram shows a cross-section of a swimming pool with two regions labeled:
- Air with refractive index n = 1.00
- Water with refractive index n = 1.33

Fredy is depicted at the bottom of the pool. A circular shape next to "Fredy" represents Fredy's eye. The setup suggests illustrating the path of light rays as they refract through the water surface at different angles.

b) What is the maximum angle from the normal in the water for rays that arrive at Fredy's eye?
