Why do white shirts feel cooler in the sunlight?
The correct answer is - White shirts feel cooler in the sunlight because they reflect light instead of absorbing it. White or lighter colored shirts reflect most of the visible wavelengths they are exposed to, while black or dark shirts absorb more wavelengths. The absorbed radiation is converted into heat, making the darker shirt warmer to wear.
Reflective Properties of White Shirts
White color is cooler in the sunlight because it does not absorb radiations coming from the sunlight. When light hits a white shirt, it reflects most of the wavelengths, including the visible light spectrum. Reflecting light means that the energy from the sunlight is not converted into heat on the body's surface.
Absorptive Properties of Darker Shirts
On the other hand, darker colored shirts absorb more wavelengths, including visible light, which results in the conversion of light energy into heat. This heat is trapped close to the body, making the wearer feel warmer when wearing a dark shirt in the sunlight.
Human Perception of Temperature
Our sensation of temperature is influenced by the amount of heat generated on our skin surface. Since white shirts reflect a significant portion of sunlight, they do not contribute to heat buildup, giving the perception of being cooler compared to dark-colored shirts that absorb more heat.
Conclusion
In conclusion, white shirts feel cooler in the sunlight because of their reflective properties, which prevent the conversion of light energy into heat on the body. This phenomenon explains why individuals prefer wearing lighter colored clothing during hot days to maintain a comfortable body temperature.
