Exam 2 topics

Exam 2 topics:


Energy

Waves

- wavelength

- frequency

- speed

- amplitude

- crests and troughs

wave speed = frequency x wavelength

(Note that the wave speed is the speed of light when you are talking about electromagnetic waves.)

mechanical vs. electromagnetic waves

harmonics on a string - "standing waves"

music - octaves (doubling the frequency); the next note on the piano (1.0594)

Doppler effect

- red shift, blue shift

electromagnetic spectrum - radio, micro, IR, visible (ROYGBV), UV, X, gamma

light reflection

light refraction

lenses and mirrors (convex and concave)

focal length/point

predicting light paths (when light is reflected or refracted)
