# A sound wave travels at a speed of 340 m/s if its wavelength is 1.5 cm what is the frequency of the wave? Will its be audible?

velocity, v = 340 m/s

wavelength, λ = 1.5 cm = 0.15 m

frequency, f = (?)

We know that

v = λf

∴340 = 0.15 * f

∴f = 340/0.15

∴

Now, the range of audible sound is 20 Hz to 20,000 Hz.

Also, as 2266.67 Hz is more than 20 Hz and less than 20 kHz, the sound wave
