Question :-

  • A Wave with a Frequency of 500 Hz is travelling at Speed of [tex] \bf {200 \: m ^{-1}} [/tex] . What is its Wavelength ?

Answer :-

  • Wavelength of the Wave is 0.4 m .

[tex] \rule {180pt} {2pt} [/tex]

Given :-

  • Frequency = 500 Hz
  • Speed = [tex] \bf {200 \: m ^{-1}} [/tex]

To Find :-

  • Wavelength = ?

Solution :-

As per the provided information in the given question, we have been given that the Frequency of the Wave is 500 Hz . Its Speed is given [tex] \bf {200 \: m ^{-1}} [/tex] . And, we have been asked to calculate the Wavelength .

For calculating the Wavelength , we will use the Formula :-

  • Wavelength = Speed / Frequency

Therefore , by Substituting the given values in the above Formula :-

⇒ Wavelength = 200 / 500

⇒ Wavelength = 2 / 5

⇒ Wavelength = 0.4

Hence :-

  • Wavelength = 0.4 m

[tex] \underline {\rule {180pt} {4pt}} [/tex]

subbhy
Wave speed = frequency x wavelength

rearrange to find wavelength

wavelength = wave speed x frequency

w.l = 200 x 500

= 10,000 m
