Friday 10/5 Lecture
Properties of Light: Friday 10/5 Lecture: When Professor Lavelle wrote v=m*s^-1 on the board was he referring to velocity? In my notebook, I wrote v as frequency, but I don't think that makes sense.

Re: Friday 10/5 Lecture
keep in mind that v= velocity, and that = frequency(curly v). But yes in that case v is velocity

Re: Friday 10/5 Lecture
I would like to add on that v in that case would be velocity because of the units correlation. However, you can also determine if it's velocity or frequency by the way it's written. v is often straight, while curly v represents frequency and often will use Hz or Hertz as units.

Re: Friday 10/5 Lecture
just remeber the difference between v for velocity and curly v for frequency.

Re: Friday 10/5 Lecture
The greek letter nu is the curly v that represents frequency (in Hertz or s^-1), while the regular v represents velocity (in m/s or m*s^-1).

Re: Friday 10/5 Lecture
Just a general tip is to remember the formulas and what you're trying to solve for. If you have to solve for kinetic energy, then you know you have to use velocity in the formula Kinetic Energy = 1/2mv^2
