Due 2/03/2009
NAME: _______________________________ ID: _________________________ 1. If the frequency of a certain FM radio wave is 100 MHz, what is the period of each individual vibration?
2. What is the frequency of a sound wave whose vibrations occur 5 ms apart? 3. The following two graphs show the same traveling wave on a string. The top one shows a snapshot of the wave at time t = 0. The bottom shows the motion at a single position at x = 0.5 m, as time elapses. these Use two graphs to answer the following questions. Displacement (m) At t = 0 s x (m)
Displacement (m) At x = 0.5 m t (second)
