Question: 1 / 2700

What is a wavelength?

The speed of a wave

The frequency of a wave

The distance between two crests of a wave

A wavelength is defined as the distance between two successive crests (or troughs) of a wave. This distance is a crucial measurement in understanding wave properties, as it directly relates to how energy travels through a medium, whether that medium is air, water, or other materials.

Wavelength is vital in various fields, such as physics, engineering, and medicine, as it influences the behavior of waves in applications ranging from radio transmissions to sound and light waves. The longer the wavelength, the lower the frequency, and conversely, the shorter the wavelength, the higher the frequency.

Understanding the concept of wavelength helps in interpreting phenomena such as the Doppler effect, where the observed frequency of a wave changes based on the relative motion between the source and the observer. Relying on this definition provides a clearer insight into wave-related studies and applications.
