Chhattisgarh Board Solutions for Chapter: Light: Reflection and Refraction from Plane Surface, Exercise 1: Exercise

Give two examples where refraction is seen in daily life.

State the reason for the position of fish in a pond is not same as it is observed from outside. 

State the reason for the bubble of air shines in water.

How we can say that mirage is an illusion?

Prove that the length of the mirror required to view the complete image of an object is half of the height of the object.

What do you mean by refraction of light? How it is different from reflection of light?

If the absolute refractive index of glass is $3/2$ and that of water is $5/4$, then find the ratio of speed of light in water and to that in glass.

A fish seems to be at a depth of $75 \mathrm{cm}$ from the surface. What is the actual distance from the surface in $\mathrm{cm}$? (Refractive index of water is $1.33$)
