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.

Step-by-step 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,

                                        $Frequency, f= \frac{Velocity}{Wavelength}$..............................(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),

                                                      $f = \frac{335}{5}$

                                                          = 67                ( $f = \frac{m}{(s)(m)} = \frac{1}{s} = s^{-1}$)

                                    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.
