Question: 1 / 400

What does wavelength measure in a wave?

The speed of the wave

The distance between successive crests of a wave

Wavelength measures the distance between successive crests (or troughs) of a wave. It reflects how far a wave travels in one cycle. For example, in a sine wave, if you take two consecutive peaks and measure the distance along the direction of propagation, that distance corresponds to the wavelength.

Understanding wavelength is essential in various fields such as physics, acoustics, and optics, as it directly influences the properties of the wave, including its frequency and speed. The relationship between wavelength and frequency is described by the equation \( v = f \times \lambda \), where \( v \) is the speed of the wave, \( f \) is the frequency, and \( \lambda \) is the wavelength. Thus, while wavelength is related to speed and frequency, it specifically defines the physical distance between repeating points on the wave, such as crests or troughs.
