define the term frequency,wavelength,velocity of sound wave.what is the relation between them?
Answers
Frequency, Wavelength, and Velocity:-
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 relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength.
The velocity, frequency and wavelength of any wave are connected by the following relationship,
v(velocity)= ν(frequency) × λ(wavelength)
Explanation:
- As a wave is moving through a medium, medium particles oscillate in their mean location. The rate of oscillations per second is called wave frequency. frequency SI Unit is Hertz(Hz).
- The interval between 2 consecutive troughs or crests is known as the wave wavelength. Wavelength unit SI is meter(m). It is denoted by the λ symbol.
- If a wave moves via a medium it causes an interruption in the medium's particles. As the interference passes along the wave's direction we conclude the wave passes. The area covered in 1 second by the interruption is known as the wave velocity. It is taken by the wavelength component, and the wave frequency.
Relation:-
The velocity, frequency and wavelength of any wave are connected by the following relationship,
v(velocity)= ν(frequency) × λ(wavelength)
