Question

The note a4, above middle c has a frequency of 440 hz. sounds travels at about 340 m/s. what is the wavelength of middle a?

Answer 1

Answer:

Wavelength of wave is 0.7727 m .

Step-by-step explanation:

Given :The note a4, above middle c has a frequency of 440 hz. sounds travels at about 340 m/s.

To Find: what is the wavelength of middle a?

Solution:

We are given that The note a4, above middle c has a frequency(f) of 440 hz .

Velocity of wave (c) = 340 m/s

Formula of wavelength: $\lambda = \frac{c}{f}$

So , wavelength = $\frac{340}{440}$

                           = $0.7727$

Thus the wavelength of wave is 0.7727 m .
