Last Full Week

This is the last full week of class for you seniors. We are having a test on sound. You'll need to know the following information:

1.     Wave Vocabulary: amplitude, frequency, wavelength, period, speed…know what each word means, how to identify that property on a graph or use an equation to find it.

2.   Graphs…a graph with distance/length on the horizontal axis gives NO information about period or frequency. A graph with time on the horizontal axis give NO information about wavelength.

3.   Equations that will be given:

V = fl        Period = 1/frequency         dist = velocity x time

4.   Use V = fl         to reason about the sounds of different objects vibrating…like the air in a bottle, or the string on a guitar.

No questions on harmonics

Go over your homework problems and check the solutions that are posted.
