For example, in an ocean wave approaching shore, shown in the figure, the incoming wave undulates with a varying local wavelength that depends in part on the depth of the sea floor compared to the wave height. The wavelength is denoted by a Greek letter lambda (λ) and is calculated in the units of length or metre. Due to the inverse relationship of frequency and wavelength, the conversion factor between gigahertz and nanometers depends on the center wavelength or frequency. The speed of sound in a medium is determined by a combination of the medium’s rigidity (or compressibility in gases) and its density. For example, red light has a wavelength of around 620 – 740 nm and blue light has a wavelength of around 445 – 500 nm. The symbol for wavelength is the Greek lambda λ, so λ = v/f.

First, solve for \lambda to obtain$$\lambda = \frac{c}{\nu} \tag{2}$$Taking the differential of equation (2) leads to$$\Delta\lambda = -\frac{c}{\nu^2}\Delta\nu. A vibration occurs during a specific period of time is known as frequency. For example, red light has a wavelength of around 620 – 740 nm and blue light has a wavelength of around 445 – 500 nm. One simple equation is used to convert between them: The wavelengths of visible light are measured in nanometres, nm (billionths of a metre) but the equation works just the same. The wavelength of audible sound range from about 17 mm to 17000 mm. Therefore, it can be seen that a wavelength can be measured or calculated by dividing wave velocity by wave frequency. Frequency and wave speed are causes. Here’s why: the quantities , and are not on equal footing in the equation. Depending on the type of wave, wavelength can be measured in meters, centimeters, or nanometers (1m = 109nm).
