Question

6. The speed of sound waves in air is 330 m/s. A sound wave has a frequency of 750 Hz.

a. What is its wavelength as it travels through air?
b. What is its period?

Answer 1

Wavelength = 0.44 meter

Time period = 0.0013 seconds

Step-by-step explanation:

Given:

Speed of sound = 330 m/s

Frequency = 750 Hz

Find:

Wavelength

Time period

Computation:

Wavelength = Velocity / Frequency

Wavelength = 330 / 750

Wavelength = 0.44 meter

Time period = 1 / Frequency

Time period = 1/750

Time period = 0.0013 seconds
