If a ray of light enters a transparent object like water or glass at an angle the path of the ray is deflected. When it emerges, it's deflected again, but in the opposite direction if the ingoing plane and the outgoing plane are parallel to one another. This effect is known as refraction.
When a parallel ray hits a convex lens this refraction causes it to emerge as a non-parallel ray and there will be a point at which the ray becomes very narrow - maybe showing as a spot of light. This is the point of focus.
If the lens is concave, the effect is reversed and the ray emerges as a steadily expanding ray.

A concave lens is thinner at the center and thicker at the edges. When parallel light rays pass through a concave lens, they are refracted outward due to the lens's shape, causing them to diverge. This divergence of light rays is what causes a concave lens to form diverging rays.

What is another name for concave lens?
Diverging lens is another name for a concave lens. It is thinner at the center than at the edges and disperses light rays outward.
What is also called a diverging lens?
A diverging lens is also known as a concave lens. This type of lens causes light rays to diverge or spread out as they pass through it. It is thinner at the center than at the edges.
Why is concave lens diverging?
A concave lens is diverging because the light rays passing through it are refracted away from each other due to the lens shape. This causes the rays to spread out when they pass through the lens, resulting in the image appearing smaller and further away.
Why a concave lens also called the diverging lens?
A concave lens is called a diverging lens because it causes light rays to spread out (diverge) as they pass through it. This results in the rays appearing to diverge away from a common point, causing the image formed by the lens to appear smaller and positioned farther away, hence diverging.
Why is a concave lens called diverging lens?
A concave lens is called a diverging lens because it causes light rays to spread out or diverge as they pass through it. This results in the rays appearing to come from a virtual focal point behind the lens, opposite to the direction of incident light.

A concave lens bends light towards its what?
A concave lens bends light away from its center, diverging the light rays.
Can a concave lens form a real image?
Never. Since the rays coming from a real object will always be diverging. The action of a concave lens is diverging action. Hence the already diverged rays will be dirverged further. Hence no chance of convergence. Only converging rays would form a real image. Hence the answer, NEVER.
Is it possible for a diverging lens to form a real image Explain?
No, a diverging lens will always form a virtual image. This is because the light rays diverge after passing through the lens, preventing them from actually converging to a real focal point where an image could be formed.
What is concave lens also called?
A concave lens is also known as a diverging lens because it causes incident light rays to diverge away from a common point known as the focal point.
Are concave lenses converging or diverging?
Concave lenses are diverging lenses. They cause light rays to spread out as if they were coming from a point behind the lens, resulting in the formation of a virtual image that appears smaller than the object.
What is the other term for concave lens?
The other term for a concave lens is a diverging lens. This type of lens causes light rays to spread out, making objects appear smaller and farther away when viewed through it.
Is a lens that is thicker at the edges than in the middle a concave lens?
No, a lens that is thicker at the edges than in the middle is a convex lens. A concave lens is thinner at the center than at the edges.
