### Variables in equations

Hi guys,

I'm a little confused about some of the variables in the equations that we recently learned. How do you guys differentiate when the "V" in the equation denotes frequency versus velocity?

I believe the "V" for frequency is actually the greek symbol "nu" so it looks a little different than the normal letter V.

I think the easiest way to differentiate between nu and velocity would to just memorize all of the ways that one of the two can be applied in chemistry. So far, I think we've only seen velocity used to calculate momentum for De Broglie's Wave Equation. As we move through the quarter it might be a good idea to note down any other application of velocity to avoid confusion.

The "v" for frequency isn't really a v but a greek letter, so I think of it more like a 'wavy' v and try to make it clear in my work. It's also helpful to know which equations use frequency and which use velocity off the top of your head.

You'll just have to pay attention to the font, because frequency is the greek letter "nu."
