Yes, it is true.
Infrared radiation is part of the electromagnetic spectrum, which includes radio waves, microwaves, visible light, ultraviolet, X rays and gamma rays. Infrared radiation has longer wavelengths than the red part of the visible spectrum (hence the name infrared for below red) and is invisible to the human eye. However humans do sense infrared as heat. So when you are warming yourself on a cold day with a roaring fire or hands around a hot drink it is the infrared radiation you are feeling.
Human beings
No human beings, as of this date.
It is probably older than human beings have lived on earth.
Bullets, the weakness of all beings with the exception of Bruce Lee.
Light and heat are very helpful to human beings, and radio has become pretty important too.
Living beings which have eyes can observe light. Nature has endowed the human eye with the sensitivity to detect electromagnetic waves within a small range of electromagnetic spectrum.

Because it's comprised of the band of wavelengths that the human eye can detect, that is, wavelengths that are 'visible' to human beings.
The region of EM spectrum absorbed by ozone is UV. It is harmful for human life.
all beings emit electromagnetic energy. transcription before translation. Translation in this conversation who makes electromagnetic amplifiers making elecromagnetic amplifiers?
X-rays are a part of the electromagnetic spectrum. It consists of electromagnetic waves that have unique characteristics based on their wavelength or frequency. Human beings can only perceive light that has a wavelength about 10-6 metres. This spectrum consists of all visible lights, from red to violet. X-rays, on the other hand have a wavelength of 10-10 metres, much beyond the range of the electromagnetic spectrum that is visible to the naked eye. It is therefore not possible to see X-rays, although all of the electromagnetic spectrum is fundamentally the same. It is the inherent property of the human eye to be able to see only the frequencies that are present in the visible spectrum

There is no evidence to the contrary. Everyone simply is. All beings possess the exact personality traits, intellect, and fiber of being to form themselves. Life is all about finding beings that exist somewhere within your own spectrum and accomplishing goals with them. Everything else is hot air.
light energy - you can see the lightkinetic energy - you can see it movingpotential energy - you can see something higher than ground level so it can fall and be converted to kinetic energy
as human eyes are sensitive to only wavelengths ranging from 400 nanometers to 700 nanometers, so human beings can see light between these limits, and the rest of the light passes unseen.
verb - to illuminate, or to set afire adjective - not heavy, or of lower caloric content adjective - of a color that is less dark noun - illumination, or a source of illumination noun (physics) - radiation : any frequency of electromagnetic radiation within the visible range for human beings. This constitutes a comparatively small range of possible electromagnetic energies. -- Briefly, light or light(s) means: 1) Electromagnetic radiation of a visible frequency or wavelength 2) A source of illumination 3) A source of fire or to set fire 4) A comparative shade of color or hue 5) Laundry that is not dark in color
