Enter the wavelength and the numerical aperture into the Calculator. The calculator will evaluate the Resolving Power from the Abbe Equation.

## Abbe Equation Formula

RP = w/(2*NA)

Variables:

- RP is the Resolving Power ()
- W is the wavelength
- NA is the numerical aperture

## How to Calculate Abbe Equation?

The following steps outline how to calculate the Abbe Equation.

- First, determine the wavelength.
- Next, determine the numerical aperture.
- Next, gather the formula from above = RP = w/(2*NA).
- Finally, calculate the Resolving Power.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **
