Exam 2 topics

Exam 2 is primarily a conceptual test.  There is not much math - see * below.


I.  Post-test, pre-wave content

how things fly & the Bernoulli Principle

energy

II.  Waves / Sound (mostly)

waves

- wavelength

- frequency

- speed

-amplitude

- crests and troughs

* wave speed = frequency x wavelength

(same equation as above, but with c for speed, when waves are electromagnetic)

mechanical vs. electromagnetic waves

EM Spectrum - recall the chart and the 7 major types of EM waves

harmonics:  how wavelength changes (* 2L/n), how frequency changes (* it increases linearly as n goes up), and how the speed (v) remains constant

* music - octaves, equal-tempered scale (1.059)

Doppler effect

- red shift, blue shift


III.  Waves / Light

light reflection

light refraction

index of refraction

lenses and mirrors (convex and concave)

real and virtual images

focal length

predicting light paths

electromagnetic spectrum again
