Infrared waves of the sun are perceived by the skin as heat
Explanation:
- A person's skin is effected if an individual is exposed to prolonged radiation from the sun and the average temperature which an individual can withstand is up to 40 degrees centigrade. If the sun's rays fall over our skin, a percentage of infrared rays enter our skin cells , causing damage to the skin.
- Infrared is the "electromagnetic spectrum region" which ranges approximately one millimeter (wavelength) from the visible region. Thermal radiation is part of the infrared waves.
- Burning charcoal, for example, does not emit light, but it emits infra red radiation felt like heat. Electronic detectors can be used to measure infrared radiation and to identify heat leakage in homes. Infrared images acquired by satellite and aircraft sensors can provide valuable information on crop health and may help us see forest fires even though covered by an invisible smoke surface.

- The sun emits infrared waves that have a spectrum of 700 nm - 1 mm, These rays have the capacity to penetrate into the earth layers and enters into earth's atmosphere, and reach the ground surface.
- These heat waves or IR rays can cause skin allergies and even rashes. These represent the amount of energy that is emitted by the sun and are critical for the earth's climate.
