Resonance: A Plague Tale Legacy has no shortage of puzzles that are light-based, ranging from simply sending mirror signals to your crew to using different hidden symbols to raise a bull statue in order to progress. Most of the puzzles you can complete on your own, however some of them do ask for a little teamwork to get things moving, but once you know the steps, it's easy to solve.
Getting light into the room
If you want to solve the puzzle with the hanging walls and the light beam, first you need to make sure the light gets to the first lens at all. In order to do that, make your way up to the platform above the entrance, where Sophia will notice that there is a platform which lets light into the room - if you stand on it. That will prompt Leni to climb up and stand there as a counter weight, allowing Sophia to go down and handle the lenses.
Redirecting the first lens
After that step is done, now it's time to use it in combination with the lenses. Since the light hits the lens to your left already, make your way to it and point it towards the one on the right.
Redirecting the second lens
Afterwards, make your way to the lens on the right and point it towards the lens that is between the two walls, on the left side of the room.
Opening the door with the final lens
The third lens is already pointed in the right direction - towards the fourth lens - so you don't need to do anything there. The final step is to go to the fourth lens and point it not at the medallion on the wall, but at the one on the door, which will prompt it to open and you can proceed.
