The product of the wavelength and frequency of a wave is equal to the speed of the wave. This relationship is expressed by the equation:
v = λ × f
Where:
- v is the speed of the wave,
- λ (lambda) is the wavelength,
- f is the frequency of the wave.
This equation shows that as the wavelength increases, the frequency decreases, and vice versa, provided the speed of the wave remains constant. This relationship is fundamental in the study of waves, including sound waves, light waves, and other types of waves.
