Due Monday for E, though you don't have to do number 1.
1. On the image below, try to use the equations to derive the wave speed equation.
2. Using this new equation, solve:
A. What is the wavelength of a concert A (440 Hz), if the speed of sound is 340 m/s?
B. What is the wavelength of a radio signal (89.7 MHz). It travels at the speed of light.
