Sunlight helps us see objects during the day as objects reflect the sunlight that falls on them. The reflected light, when received by our eyes, allows us to perceive and identify the objects in our surroundings.

Sunlight contributes to our ability to see objects during the day through the process of illumination. The Sun emits a broad spectrum of light, including visible light. When sunlight reaches objects, it interacts with their surfaces. Photons are either absorbed and re-emitted or reflected off the object. These reflected photons enter our eyes, and the lens focuses them onto the retina. The retina then converts the light signals into neural impulses, which are transmitted to the brain for interpretation. Sunlight provides the necessary illumination for clear vision, allowing us to perceive the shapes, colors, and details of objects in our surroundings.
