What is a convex lens?

Back

A convex lens is a lens that is thicker in the middle than at the edges and converges light rays to a focal point.

Front

What happens to light rays when they pass through a convex lens?

Back

Light rays passing through a convex lens bend inward and converge at a point known as the focal point.

Front

What is the focal point of a lens?

Back

The focal point is the spot where parallel light rays meet after passing through a lens.

Front

What is a concave lens?

Back

A concave lens is a lens that is thinner in the middle than at the edges and diverges light rays.

Front

What is the effect of a concave lens on light rays?

Back

A concave lens causes light rays to spread out or diverge.

Front

What is the difference between convex and concave lenses?

Back

Convex lenses are thicker in the middle and converge light rays, while concave lenses are thinner in the middle and diverge light rays.

Front

What type of lens is used to magnify images?

Back

A convex lens is used to magnify images when held close to the eye.

Front

What is a diverging lens?

Back

A diverging lens is another name for a concave lens, which spreads out light rays.

Front

How do you identify a convex lens?

Back

A convex lens is identified by its shape, which is thicker in the middle than at the edges.

Front

What is the relationship between lens shape and light behavior?

Back

The shape of a lens determines how it refracts light; convex lenses converge light, while concave lenses diverge light.
