What is wavelength and frequency?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Wavelength (λ) and frequency (f) are inversely related properties of waves. Wavelength is the spatial distance between repeating wave patterns, while frequency is the number of wave cycles that pass a point per second, measured in Hertz (Hz). They're connected by the equation v = fλ, where v is wave velocity. When frequency increases, wavelength decreases, and vice versa. For instance, radio waves have low frequencies and long wavelengths, while gamma rays have high frequencies and short wavelengths.
