He gazed at her from across the room.
No. In a room with any number of mirrors of any size, when you switch off the light or blow out the candle, the room becomes just as dark as a room without mirrors.
Because the lens has been focused depending on the available light. if you enter a darker room, your eyes have to re-adjust to allow more light through them.
You can, you just need a lighter (or something to light with) and a candle.

Light is not opaque. Standing in a room full of sunlight at mid-day, you can easily shine a flashlight across the room and make a spot on the opposite wall.

Yes, light travels through a "one way mirror" but only a small part of the light, most of the light is reflected. In fact light will travel both ways through a "one way mirror"!What makes a "one way mirror" appear to act one way is if the room on one side is brightly lit and the room on the other side is dimly lit, in the brightly lit room the reflected light from the brightly lit room swamps out the small amount of transmitted light from the dimly lit room and the mirror appears to be an ordinary mirror, but in the dimly lit room the transmitted light from the brightly lit room swamps out the small amount of reflected light from the dimly lit room and the mirror appears to be a window.
The trick to efficiently light up most rooms is to throw light across the ceiling of the room. If you are able to illuminate the ceiling of a room it will then reflect back down and provide even bright general lighting.
All of the light waves are not able to reach across the room on to the mirror

Running or sprinting would be the fastest way to get across a room.
When light travels in homogenous mediums, like air in a room, it doesn't refract visibly to our eyes. Refraction occurs when light travels between mediums of different densities, such as from air to water or glass. In the case of a flashlight in a room, the change in density is minimal and therefore not perceivable as refraction.
