Visible light is a form of electromagnetic radiation. Perhaps you mean why is it visible? Many believe this is due to the fact that the Sun's output is much higher at these frequencies therefore we have simply evolved to see the most useful part of the spectrum to us. Other animals such as bees can see more of the spectrum then us reaching into the ultraviolet range which is why some flowers have markings only visible in uv.
What else can I help you with?
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.
At what speed does all EM radiation travel at?
In a vacuum, 3x10^8 ms^-1. Basically the speed of light, it is EM radiation afterall.
What EM radiation that can be seen with the naked eye?
Visible light
What are spectrographs?
Spectrographs are instruments that separate EM radiation (primarily light) into a spectrum of frequencies and record the data. The intensity of radiation at the different frequencies can be used to ascertain information about the source of the radiation or the material through which it is passing.
What is the scientific term for light?
"electro-magnetic radiation" "electro magnetic radiation" em radiation
Is albedo an example of electromegnetic radiation?
Albedo is ameasure of how much of the Sun's light is reflected by a planet. Light is an example of EM radiation. Radiation sickness is caused only by EM radiation of the ionising sort, which is UV, x-rays, gamma rays and the like, well above the spectrum of radio waves and light.
What distance does electromagnetic radiation travel in 10.7?
In 10.7 femtoseconds, em radiation will travel 3.208 E -6 meters. EM radiation travels at the speed of light, or 299, 792, 458 m/s.
What types of EM radiation are emitted through the sun?
The sun emits a wide range of electromagnetic radiation, including radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. These different types of radiation have varying energies and wavelengths, with visible light being the most familiar form of solar radiation.
From Where does the energy carried by an EM wave come?
The electromagnetic (EM) spectrum is a name for different types of radiation. Most radiation comes from the sun. Want more info?
What is another word for light waves?
Electromagnetic waves or radiation. "Light," however, generally refers to that portion of the EM spectrum that our eyes can detect.
Is ultraviolet radiation visible or invisible?
By definition, ultra-violet light is outside the visible spectrum of EM radiation. Thus it is defined as invisible.
What type of energy transformed into chemical energy by plants?
Energy from the sun in EM radiation (visible light)
