Problem 361. Energy of a photon
⚛ ☢ ⚛ ☢ ⚛ ☢ ⚛
Given the frequency F of a photon in giga hertz.
Find energy E of this photon in giga electron volts.
Assume h, Planck's constant is about 4 femto electron-volt-second.
To maximize benefits, it may help not looking at the Test Suite before trying any solution!

Photon energy calculation is well known equation to the person who learned physics. This problem using not "J" but "eV" as the unit. Take care!

E=hf. The test cases are just wrong.

The test case should be updatet, it does not account for numerical differences. Also why not use a more accurate value for the Planck constant? As it is now one hase to reverse engineer the Planck constant from the test cases and then use that one. And then it even fails the test case...
