Why it matters in LIFE:
We use waves for our cell phones use, microwave ovens, and to listen to the radio.
Why it matters in THIS CLASS: The ideas are practical physics.

8. Legend of the Week I was born on April 22, 1904 in New York City
I graduated from Harvard summa cum laude with a degree in chemistry 
In 1939 he and his student, Hartland Snyder, predicted the existence of black holes.
“There are children playing in the streets who could solve some of my top problems in physics, because they have modes of sensory perception that I lost long ago.”
His most famous paper was co-authored by Max Born and explained the separation of nuclear motion from electric motion in the mathematical treatment of molecules.
Father of the atomic bomb
President Franklin Roosevelt established the Manhattan Project in and I was appointed its director in 1942

9. Who am I?
J.Robert Oppenheimer

16. 2. Types
Transverse: The medium vibrates perpendicular to the wave’s motion

17. Transverse or Longitudinal?

21. 4. Wave properties f = cycles/sec f = 1/3 = 0.33 Hz f = cycles/sec
It takes three seconds for a wave to go by. What is the frequency?
A runners legs go back and forth 16 times in 10 seconds. What is the frequency?
Cycles: Seconds: 3
f = cycles/sec
f = 1/3 = 0.33 Hz
Cycles: Seconds: 10
f = cycles/sec
f = 16/10 = 1.6 Hz

22. v = f  4. Wave properties v = x / t
We can use what we know to determine how fast a wave is moving.
Velocity formula?
v = x / t
v = f 
