Rearranging the wave equation to solve for Wavelength Or Frequency.
Sample question:
A hummingbird beats it wings at a rate of about 70 cycles per second, at an amplitude loud enough for you to hear.
a. What is the *frequency* of the sound wave from the wings?
b. Assuming the sound waves move with a *velocity*(speed) of 350m/s, what is the wavelength of the wave?
