The visibility of objects is facilitated by the reflection of light. In a dark room, objects are not visible, but when the room is illuminated, the objects become visible as they reflect the light that falls on them.
What enables us to see objects, and how does the visibility of objects change in a dark room compared to a lit room?

We see objects due to the interaction of light with their surfaces. In a lit room, light sources emit or reflect light, illuminating objects. Photons interact with object surfaces, reflecting into our eyes, allowing us to perceive the objects. In a dark room, without sufficient light, visibility decreases as there are fewer photons to interact with surfaces. Objects may become indistinct or invisible. The human eye’s sensitivity to light plays a crucial role in detecting objects, and adequate lighting enhances visibility, enabling us to perceive shapes, colors, and details with greater clarity compared to a poorly lit or dark environment.
