Homework Statement
Light intensity is measured by monochromator and is given by I(\lambda ) = I_{0}\lambda ^{3} How to change it to the energy scale I(h\nu ) = ?
Homework Equations
Photons energy E = h\nu, E =\frac{hc}{\lambda }
The Attempt at a Solution
It's kind of strange to relate energy with wavelenght
