In the given figure a plano-concave lens is placed on a paper on which a flower is drawn. How far above its actual position does the flower appear to be ?

A plano concave lens is silvered at the plane surface. How does it behave?

Explain why does an underwater object appears to be situated above its actual position.

As shown in figure, a plano-concave lens is placed in such a way that it becomes completely fit with plano-convex lens. Their plane surfaces are parallel. If their refractive indices are 1.6 and 1.5 respectively and radius of curvature is R, then focal length of combination is .....

In Figure, a fish watcher watches a fish through a 3.0 cm thick glass wall of a fish tank. The watcher is in level with the fish, the index of refraction of the glass is 8//5 and that of the water 4//3 . a. To the fish, how far away does the watcher appear to be ? b. To the watcher, how far away does the fish appear to be ?

Which part of a flower does protect its reproductive organs within a bud?

A concave lens of focal length 15 cm forms an image 10 cm from the lens. How far is the object placed from the lens ?

The word ‘’KVPY’’ is written on a board and viewed through different lense such that board is at a distance beyond the focal length of the lens. lgnorging magnification effects, consider the following statements (I) Image (i) has been viewed from the planar side of a plano-convex lens and image (ii) from the convex side of a plano-convex lens. (II) Image (i) has been viewed from the concave side of a plano-concave lens and image (ii) from the planar side of a plano-convex lens. (iii) Image (i) has been viewed from the cocave side of a plano-concave lens and image (ii) from the planar side of a plano-convex lens. (iv) Image (i) has been viewed from the planar side of a plano-concave lens and image (ii) from the convex side of a plano-convex lens. Which of the above statements are correct ?
