What is wavelength?

Back

Wavelength is the distance between two consecutive points of a wave, such as crest to crest or trough to trough.

Front

How does frequency relate to wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that is visible to the human eye, typically ranging from about 400 to 700 nanometers.

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves, commonly associated with heat.

Front

What is ultraviolet radiation?

Back

Ultraviolet radiation is a type of electromagnetic radiation with wavelengths shorter than visible light, known for its ability to cause sunburn.

Front

What is a prism?

Back

A prism is a transparent optical element that refracts light, breaking it into its constituent colors.
