Light Absorption

When light from the sun or a lamp hits an object, something interesting happens. The light does not just disappear. Some of the light is absorbed, which means the object takes in the light energy. Some of the light is reflected, which means it bounces off the object and travels in a different direction. The reflected light is what allows us to see the object's color.

Different objects absorb and reflect light in different amounts. Dark-colored objects absorb more light than they reflect. When they absorb light, the energy changes into heat. This is why a black car sitting in the sun feels much hotter than a white car. Light-colored objects do the opposite. They reflect most of the light that hits them and absorb very little. This keeps them cooler.

Think about wearing a dark blue shirt versus a white shirt on a sunny day. The dark shirt absorbs more light wavelengths, which are the different forms of light energy. As it absorbs this energy, it gets warmer, and you feel hotter. The white shirt reflects most wavelengths, so less energy turns into heat. This is why people in hot, sunny places often wear light-colored clothing. Understanding how objects absorb and reflect light helps us make smart choices about what to wear and what colors to use for things like cars, buildings, and even playground equipment.
