Is frequency equal to wavelength?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
No, frequency is not equal to wavelength they are inversely related. Frequency (f) measures cycles per second, while wavelength (λ) measures distance per cycle. The relationship is v = fλ, meaning as frequency increases, wavelength decreases proportionally if velocity remains constant. They are different physical quantities with different units: frequency in Hertz (Hz) and wavelength in meters (m). However, knowing one allows you to calculate the other if you know the wave's speed.
