My cheat sheet - improvements/corrections

Just finished writing this up, if someone wants to read it and give me feedback that'd be great

not planning on doing many exams since I probably have a better chance at chemistry  :P

THANKS!

What are those formulas you have involving Vp, they look quite intersting.

On my compute the picture is either tiny and unreadable or absolutely massive and I really can't be bothered downloading it and opening it on a good program...

Looks really good though, nice and succinct.

Converting peak to rms and vice versa
Vrms is the equivalent voltage of a DC power supply

Looks epic man, just wanna ask you one little thing;
On page 2, bottom left hand corner in "The Nature of matter"

You have:

p = mv = sqrt(2mE)

How'd you derive the sqrt bit?

its because Ek = 1/2mv^2
therefore root (2EK) = rootmv
to make that equal mv, multiply both sides by root m
therefore root(2EKm) = mv.

Ahh, nifty. I like it (Y)
Good stuff, I'm having a good look through it both to better my understanding and to perhaps pick up on any mistakes for your sake :)
But, job well done man. Very thorough indeed.

You might want to add how to alter the fringe separation when passing light through slits, in there somewhere?

EDIT: Nvm, you have it first thing on page two. xD

Thanks everyone, and glad to have helped some people :P
Hope the physics exam doesn't follow the pattern of all the other ones
WTF is wrong with VCAA this year... METHODS I'M LOOKING AT YOU!

Hey Tong Dong, guess you know who I am.
Anyway, you're missing equations for Power for Light, needed for calculating photons per second.
E=(P/N(photons)) = Pt and Watts from Power = Joules per second.
Also like stuff explaining why light cannot be described by wave theory if u cbl, (stopping Vo, Threshold frequency...e.t.c.) and also the stable electron equation thing; (nh/mv)=2pi-r to see if electrons fit the orbit, showing circumference of electron orbit corresponds to lambda. Also the extent of diffraction, I think it's if (L/W) is *greater* or equal to 1 for effective diffraction to occur. (accordin to Serps, so I'm not sure.)
Idk, mines got some other random crap that makes it too messy, but u can probs remember it anyway.
I'm gonna steal your electromagnetic cheat sheet lol.

Dohr Tony... you'd better try for physics or else... I'll get a 2.3 ontop of my 6 for methods.

the > or equal to 1 ratio thing is correct. thanks for the nh/mv=2pi-r didnt know that. lol. i only knew n(lambda)=circumference

lol haha, same thing I guess since de Broglie wavelength equation is lambda=(h/p) =(h/mv) and circumference is 2pi(r)* not 2pi(subtract)r lol. Thanks for the clarification on greater or equal to diffraction thing.  :)

Your definition of Faraday's law is wrong. The -ve part is Lenz's law, without the -ve it's Faraday's law.
