# What is the Math symbol for "corresponds with"

• I

## Main Question or Discussion Point

I looked on the wiki math symbol page and couldnt find one, so Im thinking "corresponds" is wrong word. Is it supposed to be equals sign with hat on it?
for example, "energy directly corresponds to wavenumber"
thanks for any help

as in if one changes so does the other ?

that's probably proportional to .... eg .. energy : wavenumber

The colon " : " is used to indicate a ratio.

The proportionality sign, " ∝ " is used to indicate that there is a direct, but unspecified, variation between two variables.

For example:

x ∝ y → y = k ⋅ x, where k is called a constant of proportionality
