Answer:
Wavelength = 0.44 meter
Time period = 0.0013 seconds
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
