Back

A wave trough is the lowest point of a wave.

Front

Define wavelength.

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is the relationship between frequency and energy in waves?

Back

Higher frequency waves have more energy.

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.
