Question

A sound wave travels at a speed of 340 m/s. If its wavelength is 2 cm, what is the frequency of the wave? Will it be in the audible range? ​

Answer 1

Answer:

Will it be in the audible range ? Speed of sound v = 340 m/s. ,Wavelength λ=2cm=0.02m. Frequency υ=? v=υλ⇒υ=vλ=3400.02=17000Hz = 17 kHz.

Answer 2

Answer:

Speed of sound v = 340 m/s. ,Wavelength

. <br> Frequency

<br>

= 17 kHz. <br> The audible range of sound wave is 20 Hz to 20 kHz. <br> Hence this is in the audible range.
