1. Find an equation that relates wavelength, wave speed and frequency. Use this for the next 2 problems. (By the way, if you don't quite know what these things mean, look them up first.)
2. Calculate the wavelength of a 440-Hz sound wave (which is concert A), if the speed of sound is 340 m/s.
3. The speed of light is approximately 3 x 10^8 m/s. What is the frequency of a 0.03-m microwave?
4. Find definitions for mechanical wave and electromagnetic wave.
