Higher than visible light, yes but not as high as x rays and gamma.
Infra red Radiation is a synonym for Heat Energy.
Infra-red ray's do not give heat merely when they come into contact with something the infra-red (light) energy is converted into thermal energy
Infra red Radiation is a synonym for Heat Energy.
Infra-red has less energy the visible light, and so it takes less energy to create.
Infra Red or heat
Kinetic, and infra red
Infra red radiation
Radiation from the sun (infra red wavelengths)
Heat is transported through Infra red. It is an electromagnetic wave
Heat lamps are just infra-red ray emitter. In simple terms they release waves containing energy. As these infra-red waves reaches the food, they transfer into heat energy and thus heating the food. In summary light energy turns into heat energy.
UV and infra-red rays are deflected by the earth.
If you actually mean infra-red light, it is simply infra-red photography. Color and b&w infra-red film as well as filters for electronic flash may still be available from specialty suppliers. If you are referring to images created by recording heat energy emissions, it is not really infra-red photography. That is correctly referred to as thermography.
