Question

What frequency sound has a (0.10 m) wavelength when the speed of sound is (340 m/s)?

a) (3400 Hz)
b) (3200 Hz)
c) (3000 Hz)
d) (2800 Hz)

Answer 1

The frequency of the sound with a wavelength of 0.10 m and a speed of sound of 340 m/s is 3400 Hz.

Step-by-step explanation:

To determine the frequency of a sound that has a wavelength of 0.10 m when the speed of sound is 340 m/s, we can use the formula for the speed of sound, which is given by v = f × λ, where v is the speed of sound, f is the frequency, and λ is the wavelength.

We can rearrange this formula to solve for frequency (f) as follows: f = v / λ

Plugging in the values gives us:

f = 340 m/s / 0.10 m

= 3400 Hz.

So the frequency of the sound is 3400 Hz, which corresponds to option a).
