Which parameter is determined by the sound source and the medium?

The correct answer, which is wavelength, is determined by both the sound source and the medium through which the sound travels. Wavelength is the physical distance between consecutive peaks (or troughs) of a wave, and it is influenced by the speed of sound in the medium and the frequency of the sound produced.

When a sound wave travels through a medium, its speed is affected by the properties of that medium, such as density and elasticity. The relationship between speed (v), frequency (f), and wavelength (λ) is described by the equation:

[ v = f \cdot \lambda ]

In this equation, the frequency is determined by the sound source, while the speed of sound can vary between different materials (like air, water, or tissues in the body). Therefore, to find the wavelength, you can rearrange the equation to:

[ \lambda = \frac{v}{f} ]

This means that knowing both the frequency emitted by the sound source and the speed of sound in the medium allows you to determine the wavelength.

Other parameters like amplitude, frequency, and intensity have different dependencies. Amplitude is related to the energy and strength of the wave but does not directly consider the medium in the
