Wavelength Calculator
Wavelength calculator is used to calculate the wavelength (λ) of a wave based on its frequency (f) and velocity (v).
What is Wavelength?
Distance between two consecutive crests (or troughs) of a wave is called Wavelength.
It is denoted by the Greek letter λ (lambda).
Formula of Wavelength:
λ = v / f
where,
- λ is the wavelength,
- v is the velocity of the wave,
- f is the frequency of the wave.
Examples Of Wavelength
Example 1:
Calculate the wavelength of light in water having a wave frequency of 12 Hz and wave velocity of 220m/s.
Solution
Step 1: Take the given data.
Wave frequency = 12 Hz
Wave velocity = 220m/s
Step 2: Take the general formula of wavelength and substitute the values of frequency and velocity.
λ = v / f
λ = 220 / 12
λ = 55/3
λ = 18.33w
Example 2:
Calculate the wave velocity of light in glass having a wave frequency of 16 Hz and wavelength of 10w.
Solution
Step 1: Take the given data.
Wave frequency = 16 Hz
Wave length = 10w
Step 2: Take the general formula of wavelength, rearrange it, and substitute the values of frequency and wavelength to it.
λ = v / f
λ * f = v
v = 10 x 16
v = 160m/s
