Question

How does the speed of the wave compare between 300 hz and 400 hz

Answer 1

The ratio between initial and final speed is 3:4

Explanation:

The speed of a wave is given by the wave equation:

$v=f\lambda$

where

v is the speed

f is the frequency of the wave

$\lambda$ is the wavelength

In this problem, we have a wave with wavelength $\lambda$ and initial frequency

$f_1 = 300 Hz$

So its speed can be written as

$v_1 = f_1 \lambda = 300 \lambda$

Later, its frequency changes to

$f_2 = 400 Hz$

Assuming that its wavelength has not changed, this means that its new speed is

$v_2 = f_2 \lambda = 400 \lambda$

By calculating the ratio between the two,

$\frac{v_1}{v_2}=\frac{3}{4}$

So, the ratio between initial and final speed is 3:4.
