Describe the relationship between frequency and... - SS2 Physics Waves and Sound Question

Frequency and wavelength are inversely proportional to each other in waves. The frequency of a wave is the number of complete wave cycles passing a point per unit time, while the wavelength is the distance between two consecutive points in phase. Mathematically, the relationship between frequency (f) and wavelength (λ) is given by the equation: c = f × λ, where c represents the speed of the wave.

 

When the frequency of a wave increases, the wavelength decreases, and vice versa. This relationship holds true for all types of waves, including light waves and sound waves. Changes in frequency and wavelength affect the nature of the wave. For example, in sound waves, an increase in frequency leads to a higher pitch, while a decrease in frequency results in a lower pitch. In light waves, higher frequencies correspond to colours towards the blue end of the visible spectrum, while lower frequencies correspond to colours towards the red end.
