1-12Here is another problem. If a wave has a velocity of 1,100 feet per second and a wavelength of 30feet, what is the frequency of the wave?By transposing the general equation:To find the velocity, rewrite the equation as:v = ILet’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:
