The Suns infrared light

Posted on October 29, 2013

Why is it that in the sun we feel warm while in the shade it is cool? Most of the warmth of the sun that we feel comes from infrared light. The majority of the light from the sun is infrared light and unlike ultra violet, it is completely safe for humans. The most interesting characteristic of infrared light is that it warms up objects without warming the air in between those objects. The easiest way to understand this is to look at the light of the sun. The sun is hot, but space between us and the sun is freezing cold yet, standing in the sun light makes us feel warm. This is because the infrared part of the sunlight warms up object directly without having to warm up the air first.
