Why is concave lens called a negative lens?
A concave lens is called a negative lens because it causes light rays passing through it to diverge, or spread out. This is in contrast to a convex lens, which converges light rays and is called a positive lens. The negative or positive designation refers to the effect the lens has on the light rays.
What is the effect when light passes through a concave lens?
When light passes through a concave lens, it diverges outward. This causes the light rays to spread apart rather than converging at a single focal point as with a convex lens. As a result, the image formed by a concave lens is virtual, upright, and reduced in size.
What is another name for concave lens?
A concave lens is otherwise known as a diverging lens.
An air bubble in water will act like concave or convex lens?
An air bubble in water will act like a concave lens. This is because the diverging effect on light rays passing through the air-water interface creates a virtual focus point on the opposite side of the bubble, similar to a concave lens.
Where will a concave lens be the thinnest?
along its axis in the center
What is the effect of a combination of concave and convex lens?
simple telephoto lens

What is Another name of convex and concave lens?
A convex lens is also known as a converging lens, while a concave lens is also known as a diverging lens.
When does a concave lens act as convex lens?
A convex lens acts as concave lens when it is kept in a medium whose optical density is higher than the lens itself. And the vice-verse is also true .i.e, a concave lens can act as convex lens too .
Is a concave lens is a diverging lens.?
False
