Light is a form of energy, specifically a wave.
Light travels in straight lines.

Light Waves and Properties

Light waves have characteristics like wavelength and frequency.
A crest is the highest point of a light wave.
A trough is the lowest point of a light wave.
Amplitude is the height of a light wave.
