Lakhmir Singh and Manjit Kaur Solutions for Chapter: Refraction of Light, Exercise 15: Questions Based on High Order Thinking Skills (HOTS)

An object is placed at the following distances from a convex lens of focal length $15 \mathrm{cm}$: Which position of the object will produce a magnified real image?

 Which position of the object will produce a magnified virtual image in the case of a convex lens of focal length $15 \mathrm{cm}$?

Which position of the object will produce a diminished real image in the case of a convex lens of focal length $15 \mathrm{cm}$?

An object is placed at the following distances from a convex lens of focal length $15 \mathrm{cm}$: Which position of the object will produce an image of same size as the object?

When an object is placed at a distance of $36 \mathrm{cm}$ from a convex lens, an image of the same size as the object is formed. What will be the nature of image formed when the object is placed at a distance of $10 \mathrm{cm}$ from the lens?

When an object is placed at a distance of $36 \mathrm{cm}$ from a convex lens, an image of the same size as the object is formed. What will be the nature of image formed when the object is placed at a distance of $20 \mathrm{cm}$ from the lens?
