\nThe phenomenon where heat is trapped inside a car parked in the sun is known as the greenhouse effect. Sunlight (short-wavelength radiation) passes through the glass windows and is absorbed by the interior surfaces of the car. These surfaces then re-radiate the energy as infrared radiation (long-wavelength heat radiation). The glass, while transparent to visible light, is largely opaque to this infrared radiation, trapping the heat inside the car and causing the temperature to rise.
\n<\/section>\n
\n– Sunlight (shortwave radiation) enters through glass.
\n– Interior absorbs sunlight and re-radiates as infrared heat (longwave radiation).
\n– Glass traps the infrared radiation, preventing heat escape.
\n<\/section>\n
\nThis process is analogous to the way greenhouse gases in the Earth’s atmosphere trap heat, contributing to global warming. Ozone depletion refers to the thinning of the ozone layer, which protects from UV radiation. Solar effect generally refers to effects caused by the sun’s activity. Cosmic ray impingement is related to high-energy particles from space.
