Light Reflection and Refraction

Absorption is the process where light energy is taken in by a material and converted into other forms of energy, such as heat, rather than being reflected or transmitted.

Refraction is the bending of light as it passes from one medium to another of different optical density, such as from air to water.

A prism is an optical element with polished, flat surfaces that refract light. Because different colors have different wavelengths, they refract at different angles, separating white light into its component colors.

The surface of water acts like a mirror when light strikes it, causing reflection. This reflection creates the image seen on the surface.

Light travels in a straight line until it interacts with matter, where it can be reflected, refracted, or absorbed.

The Moon is a non-luminous body. It appears bright because it reflects the light emitted by the Sun.

Aluminum foil is a shiny, metallic surface that acts as a good mirror, reflecting a high percentage of incident light compared to dull or matte surfaces like concrete or cloth.

Reflection is most efficient when light strikes a smooth, shiny surface, which minimizes diffuse reflection and maximizes specular reflection.

Light travels in straight lines in a uniform medium, a property known as rectilinear propagation.

Refraction is defined as the change in direction of a wave passing from one medium to another caused by its change in speed.

When light hits a surface and bounces back into the same medium, the phenomenon is called reflection.

Light is a form of electromagnetic radiation, which is a type of energy that can be perceived by the human eye.
