Refraction from a plane surface

Refraction from a plane surface

Introduction: We have already seen that refraction of light takes place when light travels from one medium to another medium. Thus the image is formed at a location where refracted rays meet. The nature of the formation of the image depends on the nature of the surface on which the light is incident. Thus the refraction can be studied under two conditions.

1) Refraction through a plane surface 

2) Refraction through a spherical surface.

In this topic, we will try to understand the phenomenon of refraction through a plane surface.

1) Refraction through a plane surface

Refraction from plane surface

Consider a coin placed in a beaker filled with water. when the coin is seen from the air, it is found that the coin appears to be at a different location (M) as shown in figure. Let R be the real depth of the coin from the surface of the water and A be the apparent depth of the coin from the surface of the water.

Mathematically,
