define the term "frequency, wavelength and velocity of the sound wave.what is relation between them?
Answers
the frequency of the wave is set by whatever is driving the oscillation in the medium. Examples are a speaker that sets up a sound wave, or the hand that shakes the end of a stretched string.
the speed of the wave is a property of the medium.
the wavelength of the wave is then determined by the frequency and speed:
λ = v/f
The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
hope it help you please mark it brainliest and follow me

What is the relationship between frequency and wavelength in sound waves?
The velocity of a wave in a given medium (air, water, etc) is fixed and is related to the physical characteristics (temperature, density, etc.) of the medium. Frequency and wavelength, therefore, are inversely proportional to each other, i.e. higher frequencies correspond to shorter wavelengths.
