Question

write the difference between concave and convex lens also write 2 uses of them​

Answer 1

$[]\huge\underbrace\blue{Answer}$

Explanation:

Concave Lens:

It can generate real and virtual objects, depending on the light source. Convex lenses are known as positive lenses, plus lenses, lenses that converge and condensers. The convex lenses are in the middle fat and on the edges thin.

Answer 2

Answer:

$\tt \red{Differences ⤵}$

$\huge\colorbox{red}{⭐Convex lenses}$

Convex Lenses are the lenses that feel massive at the cen.tre than at the edges. The curve of the lens is outward, and as the light beams pas s through the lens, it refracts them and brings them together, resulting in the convergence of light, due to which it is also named as a converging lens.

• Example: The lenses of a camera are a convex lens, as the light rays focus on per.son or object being captured.

1. A convex lens is used for the correction of hyperopia.
2. The converging lens is used in the proj ector as well.

$\huge \tt \colorbox{red}{⭐Concave \: lenses}$

Concave lenses represent the type of lenses which are slender at the cen tre than at the borders. The shape of a concave lense is round inward that bends the beams outward, causing divergence of the rays of light falling on it, so it is known as a diverging lens. This also makes the object look smaller and farther than they really are and the image formed is virtual, diminished and upright.

• Example: Concave lenses are used in the side mirrors of cars and motorbikes. They can also be used in movie projectors to spread the image.

1. Concave lens used in glasses
2. Concave lens used in peepholes.
