Standing Waves

1. Draw a sine wave. On this graph, indicate what the Amplitude and Period are. If someone just gave you this graph, how could you find the Frequency?

2. Imagine that two water waves moving in opposite directions run into each other. What will the resulting wave look like?

3. When 2 waves interfere, can the resulting wave have a larger amplitude than either of the two original waves? When?

4. What is the definition of a node?

5. For musical instruments, the sound waves produced are of a certain frequency. This frequency corresponds to the pitch of the notes that your ears hear. How can one instrument make so many different sounds?
