The frequency of a wave is related to which of the following?

The frequency of a wave is indeed related to the wavelength of the wave. In wave physics, frequency refers to the number of complete wave cycles that pass a point in one second, typically measured in hertz (Hz). Wavelength, on the other hand, is the distance between consecutive points of the same phase on a wave, such as from crest to crest or trough to trough.

The relationship between frequency and wavelength is described by the wave equation, which states that the speed of a wave is equal to the frequency multiplied by the wavelength. This relationship can be expressed as:

[ \text{Speed} = \text{Frequency} \times \text{Wavelength} ]

From this equation, we can see that if the speed of the wave is constant, an increase in frequency will result in a decrease in wavelength and vice versa. This illustrates that frequency and wavelength are inversely related when the speed of the wave remains the same.

The amplitude of the wave, while impacting the energy and intensity, does not affect the frequency directly. Similarly, while the speed of the wave and the energy can be related to frequency, they do so through different contexts and do not change the inherent relationship between frequency and wavelength.
