In physics, wavelength is a measure of the distance between two peaks or troughs in a wave. It is an important concept in various fields of science, including physics, chemistry, and biology. Wavelength is often represented by the Greek symbol lambda (λ), and is typically measured in meters. It is related to the frequency (f) of a wave through the equation: wavelength = speed of wave / frequency. This relationship means that waves with longer wavelengths have lower frequencies, while waves with shorter wavelengths have higher frequencies. Wavelength is a fundamental property of waves and is used to describe and analyze a wide range of wave phenomena, from electromagnetic waves like light and radio waves to sound waves and ocean waves.
