Light Behavior and Lens Properties

Front

What is a plane mirror?

Back

A mirror with a flat surface that reflects light to form an image.

Front

What does it mean if a material is translucent?

Back

It allows some light to pass through but not enough to see clearly through it.

Front

What is the focal point in optics?

Back

The point where light rays converge or meet after passing through a lens.

Front

What is refraction?

Back

The bending of light as it passes from one material to another.

Front

What shape does a concave lens have?

Back

An inward curved shape that spreads light rays apart.

Front

What is the difference between transparent, translucent, and opaque materials?

Back

Transparent materials allow all light to pass through, translucent materials allow some light but not clear images, and opaque materials do not allow light to pass through.

Front

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

Back

They spread apart or diverge.

Front

What is the definition of a convex lens?

Back

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

Front

What is the law of reflection?

Back

The angle of incidence is equal to the angle of reflection.

Front

What is dispersion of light?

Back

The separation of light into its different colors when it passes through a prism.
