Hi,

I am just wondering if there is a way to use the value of wavelength instead of frequency in the "Study Setting" in version 4.2. I know how to do that in version 3.5, but could not figure the trick for the new version. Thanks.

Yan

put the frequency as c_const/lambda , where lambda is you wavelength in meters.
