Reflection and Refraction

Reflection is the bouncing back of light when it hits a surface, such as a mirror.

Refraction is the bending of light as it passes from one medium to another, like from air to water.

Light travels in a straight path.

A transparent object allows most light to pass through, making it possible to see through it.

A translucent object allows some light to pass through but not enough to see clearly through it.

When light hits a mirror, it reflects back, demonstrating the principle of reflection.

The term is reflection.

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

A convex lens is thicker in the center than at the edges and converges light rays.

Reflection is the bouncing back of light, while refraction is the bending of light as it passes through different materials.
