Which object observe light?
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.
What is visible light and what portion can humans detect?
Visible light waves are the electromagnetic waves which are detected by the human eye. They make up only a small part of the electromagnetic spectrum. So, visible light is any light in which the human eye can detect.
What are the components of electromagnetic spectrum?
The electromagnetic spectrum - is simply the range of frequencies that radio waves etc travel at. This ranges from below human hearing (sub-sonic), through audible range past supersonic, broadcast radio, terrestrial television, micro-waves, satellite and beyond !
Why can you see visible light waves but not other electromagnetic waves?
Visible light consists of the band of wavelengths to which the structure of the human eye is sensitive. Radiation outside of that band may enter the eye, but there's nothing in there that responds to it, so the brain remains unaware of it.
White light is a combination of electromagnetic waves with frequencies from what?
the range of visible light.

Visible light waves are the electromagnetic waves which are detected by the human eye. They make up only a small part of the electromagnetic spectrum. So, visible light is any light in which the human eye can detect.
What is the light you can detect with your eyes?
Visible light - electromagnetic waves in the frequency range 430 to 770 teraHz.
What things can be used to detect invisible forms of electromagnetic radiation?
Different devices are used to detect different frequency ranges of electromagnetic waves. You simply can't use the same device to detect x-rays, than you would use to detect radio waves, for example.
What is the name for the range of electromagnetic waves when they are placed in order of frequency?
The answer is electromagnetic spectrum
Range of electromagnetic waves placed in a certain order is calle?
electromagnetic spectrum
Vision is what type of energy?
Vision is not any type of energy. Vision can detect the visible range of the electromagnetic spectrum by the interaction of electromagnetic waves with chemical compounds; this interaction then results in electrical impulses being sent to the brain.
What is heat by electromagnetic waves called?
The transfer of heat by electromagnetic radiation is called thermal radiation. It is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.
What are the components of electromagnetic spectrum?
The electromagnetic spectrum - is simply the range of frequencies that radio waves etc travel at. This ranges from below human hearing (sub-sonic), through audible range past supersonic, broadcast radio, terrestrial television, micro-waves, satellite and beyond !
What are the the components of electromagnetic radiation?
Electromagnetic radiation is simultaneously both waves and photons. The waves are perpendicular electrical waves and magnetic waves. Photons are massless particles. At lower frequencies/energies the waves are the easier to detect phenomenon, at higher frequencies/energies the photons are the easier to detect phenomenon, but it is always both all the time.
What is electromagnetic spectrume?
ALL the radiation from the lowest frequency to the highest.
Is the electromagnetic spectrum the same as the electromagnetic wave?
No. The spectrum means the entire range of wavelengths that electromagnetic waves can have, ranging from x-rays and shorter waves right up to the kilometre-long waves used for submarine communications and long-range navigation.
