What is the formula for wavelength λ?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The wavelength formula is λ = v/f, where:
- λ (lambda) = wavelength in meters
- v = wave velocity in meters per second
- f = frequency in Hertz
This can be rearranged from the wave equation v = fλ to solve for wavelength when you know velocity and frequency.
