Reflection, Refraction, Absorption

Front

What is Refraction?

Back

Refraction is the bending of light waves as they pass from one medium to another, caused by a change in their speed.

Front

What is Reflection?

Back

Reflection is the bouncing back of light waves when they hit a surface that does not absorb the light.

Front

What is Absorption?

Back

Absorption is the process by which a material takes in light energy, preventing it from being reflected or transmitted.

Front

What is the visible light spectrum?

Back

The visible light spectrum is the range of wavelengths of light that can be seen by the human eye, typically from about 380 nm (violet) to 750 nm (red).

Front

What happens to light when it passes through a prism?

Back

When light passes through a prism, it is refracted, causing the different colors to spread out and form a spectrum.

Front

What color of light has the longest wavelength?

Back

Red light has the longest wavelength in the visible light spectrum.

Front

What color of light has the shortest wavelength?

Back

Violet light has the shortest wavelength in the visible light spectrum.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is an example of reflection in everyday life?

Back

An example of reflection is seeing your image in a mirror.

Front

What is an example of absorption in everyday life?

Back

An example of absorption is a black shirt absorbing sunlight and becoming warm.
