Is the electromagentic spectrum can only be seen in visiable light?

Some electromagnetic waves are invisible and some aren't. Light is electromagnetic radiation, and we can see it. Radio waves aren't, and neither are x-rays or cosmic rays. All of these are electromagnetic waves.

∙ 14y agoThe definition for being invisible is not to be able to see something by ordinary means...for example...
air exists but can not be seen...
so, yes electricity is invisible...but
it is made up of electrons and magnetism, which scientists can see!

∙ 11y agoUsually when one says light waves, one is referring to Visible light.
Any light wave, and hence visible light, is an electromagnetic wave.
As an electromagnetic wave, it is also a transverse wave. The oscillating electric and magnetic fields of an electromagnetic wave in free space are oscillating with a direction perpendicular yo the direction of movement of the wave.
The velocity of an electromagnetic wave is the sped of light. This is a sensible things since light is an electromagnetic wave. In a vacuum all electromagnetic waves travel at the same speed. In matter, if the matter allows an electromagnetic wave to propagate, the speed is slower than the speed of light and in optics we say the speed is reduce by the index of refraction, v=c/n.
Electromagnetic waves, like all waves, have velocity, wavelength, frequency, amplitude and phase. As with all transverse waves, electromagnetic waves can be polarized, or we say, have a polarization.
Electromagnetic waves have electric and magnetic fields that are sinusoidal in space and time. These electromagnetic fields satisfy Maxwell's equations, i.e. the fundamental laws of electromagnetism.
There is a quantum version of electromagnetic theory called electrodynamics and that theory is the necessary edification of Maxwell's equations to describe the quantum nature of light. Thus, even when we are discussing light as photons, it is correct to say light is an electromagnetic wave as such is manifested within quantum electrodynamics.

∙ 9y agoYes. The 'visible' wavelengths are the only ones that your eyes respond to.
At other wavelengths, even if they do enter your eyes, you don't know it.
That's why microwave and intense ultraviolet can be dangerous.

are within the small range that eyes can detect.

∙ 10y agoNot unless you can see radio waves, microwaves, cellphone signals, heat waves,
ultraviolet (blacklight) waves, GPS waves, police radar waves, X-rays, etc.

What is Visible light only a small portion of?
the light spectrum
Does a prism separate light into only the visible spectrum or the entire spectrum?
Well, seeing as it seperates visible light, it follows that it only seperates that visible light into the visible spectrum. You can't make radiowaves or UV rays out of visible light.
What is color spectrum and how is it obtained?
The color spectrum is part of the electromagnetic spectrum. The color spectrum, often referred to as 'visible light' is only part of it. It is called visible light because it is the only spectrum that we can see with our eyes (we can't see x-rays, radiowaves, etc). The colors within it come in the order of ROYGBIV : Red, Orange, Yellow, Green, Blue, Indigo, Violet.
Why is it true to say that all EM radiation is light even though we can see only a small slice of the spectrum as visible light?
Visible light is a very small part of the EM spectrum and it is intellectual laziness to refer to all EM radiation as light.
Why astronomers study radiation beyond the violet end of visible light and beyond the red end of visible light?
Astronomers study as much of the spectrum of radiation as they can, and the visible spectrum is only a small segment of it.
What are the kinds of visible radiation in the electromagentic spectrum?
only the ones that have the names of colors
What is Visible light only a small portion of?
the light spectrum
Is it true or false that you can see most of the light in the spectrum?
False. People can only see the Visible Light spectrum, which is only a small section of the overall light spectrum.
Can we see most of the light in the spectrum?
No. We can only see visible light, which is only a small portion of the electromagnetic spectrum.
Is Saturn the only planet with visiable rings?
No
What is the only light visible in the electromagnetic spectrum?
the range of the spectrum that's known as "visible light"
Does a prism separate light into only the visible spectrum or the entire spectrum?
Well, seeing as it seperates visible light, it follows that it only seperates that visible light into the visible spectrum. You can't make radiowaves or UV rays out of visible light.
Is light visible or not?
Only a small piece of the light spectrum is visible to us.
Use spectrum in a sentence?
In her performance, she covered a wide spectrum of dance styles. Photosynthesis uses only a portion of the light spectrum.
Order of length of the visible spectrum?
The visible light spectrum is the only part of the spectrum that we can perceive with our eyes. It is commonly considered to be the 400nm -700 nm region. It lies between ultraviolet and Infrared region of the light spectrum.
What does the visible light spectrum consist of?
only the color white
Explain the difference between the continuous spectrum of white light and the atomic emission spectrum of an element?
The difference between continuous spectrum and the atomic emission espectrum of an element is that in emission spectrum, only certain specific frequencies of light are emitted while in a continuous spectrum, a continuous range of colors are seen in the visible light.
