Question
A radio station broadcasts at a frequency of 9000 Hz. The radio waves travel at a speed 30 m/s.Calculate the wavelength of the radio waves?
Solution
To calculate the wavelength of the radio waves, we can use the formula for the speed of a wave, which is:
Speed = Frequency x Wavelength
We know the speed (30 m/s) and the frequency (9000 Hz), so we can rearrange the formula to solve for the wavelength:
Wavelength = Speed / Frequency
Substituting the given values:
Wavelength = 30 m/s / 9000 Hz = 0.00333 meters or 3.33 millimeters.
