Answer 1

QUESTION:

Q4. Calculate the wavelength of a 10kHz sound in air at a temperature of 300 SOLUTION:

At a temperature of 300 K the speed of sound in the air is $\upsilon_{\mathrm{sound}} = 347.2\ \mathrm{m/s}$

And

$$\lambda = \frac{\upsilon_{\mathrm{sound}}}{\nu}$$ $$\lambda = \frac{347.2}{10000} = 0.03477\ \mathrm{m}$$

ANSWER:

$\lambda = 0.03477\ \mathrm{m}$
