Question

one object performs 6600 vibrations per second.if the speed of Sound in air is 330 m/s then calculate :1 time period 2 frequency3 wavelength

Answer 1

Time period = 1/6600

Velocity= wavelength/time period

= 330/6600= wavelength

Velocity= wavelength × frequency

330=330/6600× frequency

6600= frequency

Answer 2

The given information is,

N or the Number of Vibrations per second = 6600/ second

V or S or Speed of sound in air per second = 330 m/s

Calculate time by,

Time Period = 1 / N = 1 / 6600 = 0.00015.

Frequency = Time period

Wavelength = Velocity / Time period

Therefore, Wavelength = 330 / 0.00015.

This is how you can calculate the period, Frequency and velocity.
