Wavelength is the distance between two consecutive points in phase, such as two crests or two troughs, in a wave. It plays a crucial role in determining the characteristics and behaviour of different types of waves. The wavelength of a wave affects how the wave interacts with its medium and the environment.

 

In sound waves, the wavelength determines the perceived pitch of the sound. Higher-frequency sounds have shorter wavelengths and are perceived as higher-pitched, while lower-frequency sounds have longer wavelengths and are perceived as lower-pitched. For example, a high-pitched whistle produces sound waves with shorter wavelengths compared to a low-pitched drum.

 

In electromagnetic waves, the wavelength determines the colour of the light. Different wavelengths of visible light correspond to different colours. For instance, red light has a longer wavelength, while violet light has a shorter wavelength. The study of wavelengths in electromagnetic waves is essential in various fields, including optics and astronomy.
