Question

The wavelength of a sound emitted by by a a source is l.7 × 10-2m calculate frequency of the sound if it's velocity is 334.4ms-1

Answer 1

Answer:

Solution

The relationship between velocity, frequency and wavelength of a wave is given by the formula:

v=f×λv=f×λ

Here, Velocity, v=343.4ms−1v=343.4ms-1

Frequency, f=?f=? (To be calculated)

And, Wavelength, λ=1.7×10−2mλ=1.7×10-2m

So, putting these values in the above formula, we get:

343.4=f×1.7×10−2343.4=f×1.7×10-2

f=343.41.7×10−2f=343.41.7×10-2

f=3434×10217f=3434×10217

f=2.02×104Hzf=2.02×104Hz

Thus, the frequency of sound is 2.02×1042.02×104 hertz.
