Question

What is the wavelength of a 3128.8 Hz pitch?

Answer 1

We can find the wavelength of the pitch from the formula:

$$\lambda = \dfrac{c}{f},$$

here, $\lambda$ is the wavelength of the pitch, $c$ is the speed of the light and $f$ is the frequency of the pitch.

Then, we get:

$$\lambda = \dfrac{c}{f} = \dfrac{3 \cdot 10^8 \dfrac{m}{s}}{3128.8 Hz} = 9.58 \cdot 10^4 m.$$

Answer:

$\lambda = 9.58 \cdot 10^4 m.$
