Wave Basics & Properties of Sound

Sound waves travel at $350$ m/s through a warm air and at $3500$ m/s through brass. Which of the following is correct about the wavelength of a $700$ Hz accoustic wave as it enters brass from warm air?

Show answer and solution

Answer: (c)

Frequency does not change on entering a new medium, so $\lambda = \frac{v}{n} \propto v$ .
$\frac{\lambda_{brass}}{\lambda_{air}} = \frac{3500}{350} = 10$
So the answer is (c) it increases by a factor $10$ .
