Notes

3 pages
page 1: drawings - 2 charges, 1 magnet, 1 lens, 1 reflection/refraction (diagrams to explain things like finding images, not snell's law), 1 circuit
don't need to print, but highly recommend print

part 2: questions n problems, write answers or 4-part calc
lengthy circuit problems broken up - not one question, equivalent resistance f parallel part, or second parallel part,

2:1, 3:2 ratios good
bar magnet, horseshoe magnet, 2 bar magnets for drawing

2 extra circuit problems - *** good indication of final level of complexity

no waves! refraction until internal reflection will have wave behavior but only rays, don't need to draw rays refracting but need calculations bcuz related to critical angle like prism problem

if hit boundary less than critical angle -> both reflect and refract
greater than critical angle - only reflect
- ray from air into glass - will not reflect
internal reflection - high to low or low to high
how much ray of light refracts from air into glass, hits another aide of glass at another angle, angle greater than or less than critical angle
greater than critical angle -> internal reflection
less than critical angle -> some can refract, some can reflect
at critical angle-> at 90deg, but in practice you don't see it,
- at critical angle or greater -> internal reflection

no need protractor, will need straightedge 100%

electron moving towards wall magnetic field to right, direction and magnitude of force given velocity of election
coulombs law***, snell's law, critical angle calculation

final willl not have ray digrams or numerical calculations with lenses
YES MIRRORS NO LENSES but still some lenses just not the stuff above

graph on lab? check it

if there's a dashed line on top of a solid line just show the arrow he'll understand
- forget to show the refracted ray and only show it extending back

ALWAYS PUT ARROWS ON RAYS OR YOU'LL GET DINGED

* "a _____ mirror is analogous to a _______ lens" is fair game on the final

diverging lens: concave lens
- common mistake: the parallel ray they'll make it go diverge @ focal point, but its a diverging lens so the rays will diverge away from the axis & focal point
- same for the ray that goes down through the first focal point

don't need to know equation for faraday's law for emf

fe=qeb do you need sintheta part of that
- all three things will always be mutually perpendicular
