The wave velocity (v), the wavelength (λ), and frequency (f) are related by the equation:
v = fλ
where:
– v, the wave velocity, is measured in meters per second (m/s),
– f , the frequency, is measured in hertz (Hz)
– λ, the wavelength, is measured in meters (m).
This equation proves that the speed of a wave is the product of its frequency and wavelength.
A mechanical wave needs a medium (air, water, or solids) in which to propagate. Since it travels along compressions and rarefactions in a medium, sound waves are mechanical waves. Light waves, radio waves, and X-rays are electromagnetic waves, unrelated to a medium and certainly able to travel throuRead more
