Detailed Solution

Wavelength means the distance between two consecutive crests or troughs of a wave. Waves are common in nature, whether in water, sound, or light. To study waves, scientists use the concept of wavelength, which describes the length of one complete wave cycle.

Definition of Wavelength

Wavelength is the distance between two identical points in a wave, usually measured from crest to crest or trough to trough. It is represented by the Greek letter λ (lambda).

Formula of Wavelength

The formula to calculate wavelength is:

λ = v / f

λ = wavelength
v = velocity of the wave
f = frequency of the wave

Types of Waves and Wavelength

Sound Waves: Wavelength determines pitch and tone.
Light Waves: Different wavelengths create different colors.
Water Waves: Wavelength affects wave speed and energy.
Electromagnetic Waves: Range from long radio waves to short gamma rays.

Examples of Wavelengths

Type of Wave	Approximate Wavelength
Radio Waves	1 meter to several kilometers
Visible Light	400–700 nanometers
Sound Waves	2 cm to 17 meters (depending on frequency)
