When infrared radiation reaches a shiny surface, such as a mirror or polished metal, it is mostly reflected back rather than absorbed. Shiny surfaces have high reflectivity, which means they can bounce back a significant amount of infrared radiation. This property of shiny surfaces is why they are often used in applications like solar reflectors to maximize heat reflection.
The shortwave radiation that reaches Earth's surface and is not reflected is absorbed by the surface, warming it up.
Longer wavelength infrared radiation reaches Earth. This type of infrared radiation is also known as thermal infrared, which is emitted by the Earth's surface and is an important component of the Earth's energy budget. Shorter wavelength infrared, such as near-infrared, is mostly absorbed by the atmosphere and does not reach the surface.
The Sun emits infrared radiation, as well as a broad spectrum of other rays of electromagnetic radiation. It is the infrared band, that just beyond (and just longer in wavelength) what we see as the color red, which reacts with matter to increase its temperature. Infrared from sunlight heats the Earth's surface and atmosphere.
A dull surface is a better absorber of infrared radiation heat compared to a shiny surface. The rough texture of a dull surface allows for more absorption of infrared radiation, while a shiny surface reflects much of the radiation.
The sun emits various types of electromagnetic radiation, but the majority of the radiation that reaches Earth's surface is in the form of visible light. This includes wavelengths that range from ultraviolet to infrared.
Most of the solar radiation is absorbed when it reaches the surface of the earth. Some of the solar radiation is also absorbed in the atmosphere.

The greenhouse gas effect primarily traps infrared radiation on the Earth's surface. When the sun's energy reaches the Earth, it is absorbed and then re-radiated as infrared radiation. Greenhouse gases, such as carbon dioxide and methane, absorb and re-emit this infrared radiation, preventing it from escaping back into space and thus warming the planet.

Greenhouse gases primarily trap infrared radiation emitted by the Earth's surface. When sunlight reaches the Earth, it is absorbed and re-emitted as infrared radiation. Greenhouse gases, such as carbon dioxide and methane, absorb some of this infrared radiation and re-radiate it in all directions, including back towards the Earth's surface, contributing to the greenhouse effect and warming the atmosphere.
When radiation reaches Earth's surface, it can be absorbed, reflected, or scattered. The amount of radiation that is absorbed can contribute to heating of the surface and atmosphere. This process is fundamental for maintaining Earth's energy balance and climate.
Twenty percent of the radiation from the sun refers to the portion of solar energy that reaches the Earth's atmosphere. This radiation includes visible light, ultraviolet light, and infrared radiation, which are essential for life on Earth. The remaining 80 percent is absorbed or scattered by the atmosphere before it reaches the surface. Ultimately, the radiation that reaches the Earth's surface is crucial for climate, weather patterns, and supporting ecosystems.

Energy from the sun that reaches Earth is primarily in the form of visible light, infrared radiation, and ultraviolet (UV) radiation. UV radiation is responsible for causing sunburns and can lead to skin cancer, while infrared radiation contributes to the warming of the Earth's surface. Together, these forms of solar energy drive various processes, including photosynthesis and the Earth's climate system.
