What is the full formula for frequencys and wavelengths?

The wavelength formula is λ = v/f
where
λ = wavelength of a sound wave or electromagnetic wave
v = the speed of propagation of the wave,
f = frequency of the wave in 1/s = Hz.

c=nu*lambda
c is speed of light = 3 x 108 m/s
nu (the Greek letter) is frequency in sec-1
lambda (the Greek letter) is wavelength in meters.

To calculate the wavelength of a sound wave or electromagnetic wave, you can use the formula:

λ = v/f

Here, λ represents the wavelength, v represents the speed of propagation of the wave, and f represents the frequency of the wave in hertz (Hz).

Similarly, for the speed of light, you can use the formula:

c = ν * λ

Here, c represents the speed of light, which is approximately 3 x 10^8 meters per second. ν (nu), which is the Greek letter, represents the frequency in inverse seconds (sec^-1), and λ (lambda), also a Greek letter, represents the wavelength in meters.

By plugging in the appropriate values into these formulas, you can calculate the wavelength or frequency of a wave.
