Question

A vuvuzela produces a wave that travels at 335 m/s. The distance from one crest to the following crest is other is 5 m. What is frequency of the wave?

Answer 1

The frequency of the wave is 67
`s^(-1)` or Hz , if a wave travels at 335 m/s and the distance from one crest to the following crest is other is 5 m.

Explanation:

The given is,

Wave travels at 335 m/s

Distance from from crest to the following crest is 5m

Step:1

Formula to calculate the Frequency of wave is,

`Frequency, f= (Velocity)/(Wavelength)`..............................(1)

From given values,

Velocity = 335 m/s

Wavelength = 5 m

( wavelength - The distance from one crest to the following crest)

From the equation (1),

`f = (335)/(5)`

= 67 (
`f = (m)/((s)(m)) = (1)/(s) = s^(-1)`)

frequency, f = 67
`s^(-1)`

(∵
`s^(-1) = Hz`)

Frequency, f = 67 Hz

Result:

The frequency of the wave is 67
`s^(-1)` or Hz , if a wave travels at 335 m/s and the distance from one crest to the following crest is other is 5 m.
