Front

What happens to the brightness of a light wave with higher amplitude?

Back

A higher amplitude light wave will be brighter.

What happens to the brightness of a light wave with lower amplitude?

Back

A lower amplitude light wave will be dimmer.

Front

What is the relationship between wavelength and frequency in waves?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.
