Where does infrared heat come from?
Infrared lies between the visible and microwave portions of the electromagnetic spectrum. Infrared waves that are near to visible light do not generate heat and are used in TV remote controls. Infrared waves that are far from the visible end of the light spectrum are thermal and generate heat. The infrared heat from the sun, a lamp or a radiator is a type of far infrared radiation.
How is infrared radiation different from visible radiation?
Both are examples of electromagnetic radiation. Infrared has a longer wavelength (lower frequency) than visible light. Of course visible light is visible to humans and infrared is not (although long wave Infrared is sensible to humans as heat).
What lamp will show invisible heat radiation?
An infrared lamp will show invisible heat radiation. Infrared lamps emit infrared light, which is not visible to the human eye but can be felt as heat due to its longer wavelength compared to visible light.
Which color is the best absorber of heat?
Black is the best absorber of heat because it absorbs all colors in the visible light spectrum and converts them into heat.
What kind of radiation do we experience as invisible heat?
Invisible heat radiated from objects is in the form of infrared radiation. This type of radiation is not visible to the human eye but can be felt as heat when it strikes the skin.
What is the difference between light rays and heat radation?
Light rays are visible and have higher frequency compared to that of heat radiation Heat radiation is nothing but infra red which is not visible to human eyes. They have longer wavelength compared to that of visible light
What do you use to make invisible ink visible?
if its milk you heat it
What type of heat transfer is invisible and visible lights?
radiation
Which layer of the sun gives off heat and light?
The photosphere gives off heat and visible light.

What EM waves are emitted by fire?
Light (visible) and heat (infrared)
Example of how infrared waves and visible light are important in your life?
Infrared waves warm you providing heat and visible waves enable you to see.
How visible light and infrared energy warms earth?
by absorbing them and convert heat
Does Heat have shorter wavelengths than visible light?
No. Heat is infrared radiation ("infra" means "lower"). Lower frequency means longer wavelength. All radiation is captured by antennas that resonate at the frequency of the radiation. The "antennas" for visible light are electrons that use the radiation to jump into excited states and cause optical neurons to fire. The "antennas" of heat (infrared) are bigger -- they are molecules that jiggle faster when the radiation hits them. That jiggling is heat.
Which color is the best absorber of heat?
Black is the best absorber of heat because it absorbs all colors in the visible light spectrum and converts them into heat.
