(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Just going over some practice questions, and one of them is:

1. Verify the value of the constant, 1240, in the Duane-Hunt relation.

2. Relevant equations

E(eV) = 1240/lambda(nm)

3. The attempt at a solution

I know it is used as a quick method in finding how much energy is involved when a molecule absorbs a photon of light. I therefore know how to use it in a question. However, I'm stumped as to verifying the actual value of the constant. Any insight is appreciated!
