# PlanckRadiationLaw not working in 11.3

PlanckRadiationLaw is a function that returns the properties of a wavelength in a specific temperature.

PlanckRadiationLaw[Quantity[10000, "Kelvins"], Quantity[500, "Nanometers"]]


As shown in help But in this version, v11.3, if I run the code in help, it displayed error with no reason. Why?

• It works fine on my MMA version 11.3. – Subho May 4 '18 at 10:23
