Question

the units of certain parameters of a mechanical waves are givens name the corresponding parameter of mechanical wave and find each:<br />metre<br />metre per second<br />hertz <br />second

Answer 1

Sound is a form of energy which travels in the form of mechanical waves.
The following are the characteristics/ parameters of sound wave:
1. Wave length: The distance between two consecutive compression or rarefactions is called wavelength.
S.I units are meter.
2.Amplitude:
The maximum displacement caused by vibrating particles from it's mean position.
S.i unit is meter.
3.Frequency:
The number of oscillation completed by an oscillating body per second is called frequency.
S.I units are Hertz.
4.Time period: TIME TAKEN to complete one vibration
S.I unit: second.
5. Speed of sound wave:
The distance by which a point on the wave such as compression or a rarefactions travels in unit TIME is called speed of sound wave.
S.i unit: m/ s.
