One laser in front of another. The light from the rear laser is of a frequency that can pass through the laser at the front.
I swear I will keep going until there is a practical method that theoretically works.
I don't understand why combining two beams will force all beams to be reflected...
This is just a thought experiment so I am only considering what happens when you apply the principles of classical physics (or perhaps it will take more than just classical physics) to this scenario. The practical details should be irrelevant because only the principles are being tested here...
The energy and momentum of a closed system is always conserved.
If a laser can emit perfectly parallel and perfectly superimposed light waves (occupy the exact same space) that are perfectly 180° out of phase and of the same frequency, what can be said about the energy and momentum of the...
