Wavelength Calculator

Enter the wave speed and the wave frequency. The wavelength calculator will evaluate and display the total length of the wave.

Wavelength Formula

The following formula can be used to calculate a wavelength given the frequency and speed (velocity).

w = V / f

• Where w is the wavelength (m)
• V is the wave speed (m/s)
• f is the frequency (hz)

To calculate the wavelength, divide the wave speed by the wave frequency.

Wavelength Definition

A wavelength is a total distance a wave travels as it goes through one propagation. Think of a waveform and the distance of one propagation is from the start to crest to trough to the midpoint again.

Are wavelength and frequency directly or inversely proportion?

A wavelength of an oscillating object is inversely proportional to the frequency. This can be seen in the equation w= v/f. As frequency decreases, the wavelength increase, and as frequency increases, the wavelength decreases. What can also be seen from the equation is that the wavelength is directly proportional to the velocity of the wave.

Can a wavelength be negative?

A wavelength cannot be negative. Since speed and frequency cannot be negative, and these are the attributes that makeup wavelength, the result is that the wavelength can also not be negative.

What are the units for wavelength?

The standard units for wavelength are meters. To derive meters from the formula for wavelength, the speed must be in m/s, and the frequency must be measured in hertz (Hz = 1/s).

What properties does wavelength affect?

The wavelength can affect any related properties of a wave. These include wave speed, frequency, energy, and amplitude.
