### Variables and what they mean

I'm still a little confused about what lambda and v mean in equations, as I tend to get them mixed up.

The lamda is a letter of the Greek alphabet that is used to represent wavelength (it looks like a squiggly v), whereas the lowercase v stands for frequency.

An easy way to remember that lambda is wavelength is to notice that it kind of looks like a wave in an ocean. V is for frequency and doesn’t look like a wave.

Lambda is wavelength and 'v' is frequency!

lamda is the upside down v with a little edge at the top and it symbolizes wavelength and the v is frequency

The greek letter lambda stands for wavelength while the v is the lowercase greek letter nu which stands for frequency.

Lambda is the Greek letter used for wavelength, and "v" is frequency.

### Re: Variables and what they mean

Lambda represents wavelength and v (squiggly) stands for frequency. It's kind easy to mix up frequency and velocity (velocity's variable is lower-case v).

lambda is the wavelength of a wave. v is the frequency of a wave.

Be careful about mixing up the variables for frequency and velocity! The frequency variable is more curved than the regular v used for velocity.
