/// # Description
///
/// Computes Ernst Abbe's diffraction limit for a microscope using:
///
/// ```text
/// d = wavelength / 2 * NA
/// ```
///
/// Where `NA` is the numerical aperture of the objective.
///
/// # Arguments
///
/// * `wavelength`: The wavelength of light in nanometers.
/// * `na`: The numerical aperture.
///
/// # Returns
///
/// * `f64`: Abbe's diffraction limit.
