Question

1. What is the difference between
a concave lens and a convex
lens? Explain with the help of
diagrams.​

Answer 1

Answer:

In the convex lens, the curve is outward facing, whereas, in the concave lens, the curve faces inward. When the light rays pass through the convex lens, it converges the light rays and focuses on one point. ... On the contrary, the image formed by the concave lens is erect, virtual and smaller, than the object.

Answer 2

Answer:

1. Convex lens:

• In the convex lens, the curve is outward

In the convex lens, the curve is outward facing,

• facing,When the light rays pass through the convex lens, it converges the light rays and focuses on one point.

2. Concave lens:

• in the concave lens, the curve faces inward.

• in the concave lens, the curve faces inward.On the other hand, when the light rays go through the concave lens, it diverges the beams, i.e. they spread out.
