AP PSYCHOLOGY

Detailed explanation-1: -The wavelength of a wave describes how long the wave is. The distance from the “crest” (top) of one wave to the crest of the next wave is the wavelength.

Detailed explanation-2: -The horizontal distance between two adjacent crests or troughs is known as the wavelength.

Detailed explanation-3: -wavelength| The distance between one peak or crest of a wave of light, heat, or other energy and the next corresponding peak or crest.

Detailed explanation-4: -The highest part of the wave is called the crest. The lowest part is called the trough. The wave height is the overall vertical change in height between the crest and the trough and distance between two successive crests (or troughs) is the length of the wave or wavelength.

Detailed explanation-5: -The wavelength of a sound, therefore, is the distance between adjacent identical parts of a sound wave. Just as the distance between adjacent crests in a transverse wave is one wavelength, the distance between adjacent compressions in a sound wave is also one wavelength, as shown in Figure 14.7.
