It is concave lens
Yes, this is a concave lens. It is also called a diverging lens because it causes light rays to spread out.
Concave lens is called a negative lens because it has a negative focal length.
False
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 .
