Answer 2

Answer:

Concave and Convex lens.

Explanation:

Convex lens:

The convex lens is the lens that can be used to converge all the light going in different directions. The Convex lens is the lens that the thicker at the middle and thinner at the end. Which is used to focus light and the function of the convex lens is the same as the human eyes. It can be changed according to the distance of the object. It is used to converge the image. Having a positive focal length.

Concave lens:

The concave lens can be used to disperse all the light coming from the source into multiple directions Where the lens is thinner at the middle and thicker in the middle. It can be used to disperse light. Which is always upright, diminished and virtual. Having a negative focal length.
