Draw ray diagrams showing the image formation by a convex mirror when an object is placed at finite distance from the mirror.

A student focussed the image of a candle flame on a white screen using a convex lens. He noted down the position of the candle screen and the lens as under

Position of Candle $=12.0 \mathrm{cm}$

Position of convex lens $=50.0 \mathrm{cm}$

Position of the screen $=88.0 \mathrm{cm}$

What is the focal length of the convex lens?

A student focussed the image of a candle flame on a white screen using a convex lens. He noted down the position of the candle screen and the lens as under

Position of Candle $=12.0 \mathrm{cm}$

Position of convex lens $=50.0 \mathrm{cm}$

Position of the screen $=88.0 \mathrm{cm}$

Where will the image be formed if he shifts the candle towards the lens at a position of $31.0 \mathrm{cm}$?

A student focussed the image of a candle flame on a white screen using a convex lens. He noted down the position of the candle screen and the lens as under

Position of Candle $=12.0 \mathrm{cm}$

Position of convex lens $=50.0 \mathrm{cm}$

Position of the screen $=88.0 \mathrm{cm}$

What will be the nature of the image formed if he further shifts the candle towards the lens from position $31.0 \mathrm{cm}$.

 A student focussed the image of a candle flame on a white screen using a convex lens. He noted down the position of the candle screen and the lens as under:

Position of Candle $=12.0 \mathrm{cm}$

Position of convex lens $=50.0 \mathrm{cm}$

Position of the screen $=88.0 \mathrm{cm}$

Draw a ray diagram to show the formation of the image in case if he further shifts the candle towards the lens from position $31.0 \mathrm{cm}$.
