of 342m/s . If the
t wavelength is
-1.5cm, what is the
frequency of the
I wave? will it be audible ?​

Answer 1

Answer:

A sound wave travels at a speed of 342m/s .If the wavelength os -1.5cm,what is the frequency of the wave ?Will it be audible?

Answer 2

Explanation:

Here,

wave length(l)=1.5cm

speed of sound(v)=342m/s

frequency(f)=?

Now,

v=f × l

or,342=f×1.5cm

or,342÷1.5=f

or,228 hz=f

∵frequency of the I wave is 228hz
