Question

. Observe the figures given in Figure 15.1 carefully.

The given figures show the path of light through lenses of two different types, represented by

rectangular boxes A and B. What is the nature of lenses A and B?​

Answer 1

Box A - covex lens Box B - concave lens in given figure, nature of lens A is convex as the convex lens generally converges the light rays falling on it i.e it bends the rays inwards. Convex lens is also called 'converging lens’. nature of lens B is concave as the concave lens generally diverges the light rays falling on it i.e it bends the rays outwards. Concave lens is also called 'Diverging lens’.
