In a magical room, Aarav has the ability to see through walls, but only when he is in complete darkness. There is a light switch outside the room which Mahira can operate, and inside the room, one wall is transparent only to those with X-ray vision like Aarav's. Aarav is looking to see what is behind this transparent wall. Initially, the room is brightly lit and Aarav can't use his X-ray vision. Mahira is outside and is aware of Aarav's ability. What should happen next for Aarav to see what is behind the transparent wall?
Respond very briefly.
To enable Aarav to see what is behind the transparent wall, Mahira should turn off the light switch, plunging the room into complete darkness. Once the room is dark, Aarav's X-ray vision will activate, allowing him to see through the wall that is transparent only to his special vision. Since Aarav's ability requires complete darkness, and the wall is transparent solely under the condition of his X-ray vision, Mahira's action of turning off the light is the necessary next step.
