I want to express this two equations

[YulsLaw]

Hello, everyone^^

I want to express this 2 eqtions.

so, I tried "Eqation Nodes", "For loop", and "shift register".

But occurred problem.

The problem is a 2 variance in Equation Nodes.

I wanted first time calculate wavelength and then x.

But I didn't success.

I want i start from 750 to 850 in Sigma.

And express x-axial "x" and y-axial "I(Intensity)"

I mean I want to express graph in this equations.

If you have a solution, I want to listen your solution and advices.

Help me, Plz.

Thank you.
