IV Review of Lesson 9: Waves and Fluids
A. Waves
1. Length, l
2. Frequency, n
88 Mhz – 108 MHz FM
3.8 m
530 KHz – 1710 KHz
Light, v = c = 300,000,000 m/s
= pitch in sound
Sound, v = 340 m/s
3. Period, P = 1/n
4. Amplitude, A
5. Speed v = l n
6. Types
7. Other

B. Fluid Dynamics
1. Definition of “fluid”
2. And, defn of “dynamics”
3. Density; r = M/V; g/cm3.
4. Pressure; P = F/A; Pascal; 1.0 N/m2.
Pascal; 1013 mB = ATM; 14.7 lb/in2. Mm of Hg; inches of Hg; ATM
5. Bernoulli’s Law – pressure differences between surfaces
6. Archimede’s Principle – displacement of fluids by masses
And more….

V Lesson 10: Density, Archimedes, Bernoulli
Examples of Aviation: airplanes, gliders, helicopters, and similar.

VI Laboratory Exercise 10: Archimedes, Liquids, and Solids
