Manipur Board Solutions for Chapter: Light, Exercise 2: Try to answer

A concentrated image of the Sun can be focussed at $50 \mathrm{cm}$ away from a mirror. What is the focal length (in centimetres) of the mirror?

A concave mirror forms a real image having the same size as the object at a distance of $40 \mathrm{cm}$ in front of the mirror. What is the focal length (in centimetres) of the mirror?

An object is placed at a distance of $50 \mathrm{cm}$ in front of a concave mirror of focal length $25 \mathrm{cm}$. Find the image distance. If the object is $10 \mathrm{cm}$ high what will be the nature and size of the image?

An object is placed at a distance of $50 \mathrm{cm}$ in front of a convex mirror of focal length $25 \mathrm{cm}$. Find the image distance. What will be its nature?

An object is placed at a distance of $15 \mathrm{cm}$ in front of a concave mirror of focal length $30 \mathrm{cm}$. Find the nature and position of the image?
