Visual Representation of a Wave
A standard diagram of a wave depicts it as an oscillating line moving equally above and below a central horizontal axis. The highest points on this line are the crests, and the lowest points are the troughs. The horizontal distance between two consecutive peaks is labeled as the wavelength, while the vertical distance from the central axis to a crest or a trough is labeled as the amplitude.

Visual Representation of a Wave
Timbre as a Perceptual Quality of Sound
Consider two light waves, Wave A and Wave B. Wave B has a greater amplitude (height) and a longer wavelength (distance between peaks) than Wave A. How would the light from Wave B be perceived compared to the light from Wave A?
