INFRARED ENERGY.
Infrared radiation (IR), or infrared light, is a type of radiant energy that's invisible to human eyes but that we can feel as heat. ... From highest to lowest frequency, electromagnetic radiation includes gamma-rays, X-rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.Feb 27,2019
What is infrared energy used for?
One of the most common uses of infrared radiation is in heat-sensitive thermal imaging cameras. These can be used to study human and animal body heat patterns, but more often, they are used as night-vision cameras. These have uses in warfare, as security cameras and in nocturnal animal research.Sep 22, 2021
What is an example of infrared energy?
Image result for INFRARED ENERGY.
When an object is not quite hot enough to radiate visible light, it will emit most of its energy in the infrared. For example, hot charcoal may not give off light but it does emit infrared radiation which we feel as heat.What is the effect of infrared energy?
Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging.Jun 7, 2018
The warmer the object, the more infrared radiation it emits.
Is infrared the same as heat?
Infrared is radiated heat: the feeling of warmth from the sun on your face; the heat from a coal fire, or a toaster. It is even the same form of heat emitted by your own body. ... Infrared waves travel through the air and when they touch a surface, heat energy is released regardless of the surrounding air temperature.
