When light hits a shiny surface, it reflects off the surface, which is why we can see our reflection in mirrors or shiny objects.

Front

What is reflection of light?

Back

Reflection of light is the bouncing back of light rays when they hit a surface. This is how we see objects around us.

Front

What is refraction of light?

Back

Refraction of light is the bending of light rays as they pass from one medium to another, such as from air into water.

Front

What is absorption of light?

Back

Absorption of light occurs when light rays are taken in by a material, converting the light energy into other forms of energy, usually heat.

Front

What is transmission of light?

Back

Transmission of light is the passing of light through a material without being absorbed or reflected.

Front

What is the role of a prism in light energy?

Back

A prism can refract light and separate it into its different colors, creating a spectrum.

Front

What is the difference between reflection and refraction?

Back

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

Front

What is an example of light being refracted?

Back

An example of light being refracted is when a straw appears bent when placed in a glass of water.

Front

How does light travel?

Back

Light travels in straight lines until it hits an object or medium that causes it to reflect, refract, or be absorbed.
