Question

An F note has a frequency of 698.46 Hz. Calculate its wavelength in meters. Sound travels at 343 m/s

Question 3 options:

2.04 m


0.491 m


2.04 ft


0.491 ft

Answer 1

(b) 0.491m

Step-by-step explanation:

Given:

Frequency, f = 698.46Hz

Velocity, v = 343m/s

Wavelength, λ = ?

We know:

velocity = wavelength X frequency

Substituting the values in the formula we get:

`343 = wavelength X 698.46\\\\Wavelength = (343)/(698.46) \\\\Wavelength = 0.491m`

Therefore, the wavelength of the sound is 0.491m
