Here is another problem. If a wave has a velocity of 1,100 feet per second and a wavelength of 30
feet, what is the frequency of the wave?
By transposing the general equation:
To find the velocity, rewrite the equation as:
v = I
Let’s work one more problem, this time using the metric system.
Suppose the wavelength is 0.4 meters and the frequency is 12 kHz. What is the velocity?
Use the formula:
