Anything that can reflect light is only visible to an eye... others which cannot are dark..
This might be a description of spectrum analysis. In spectrum analysis, we look at a range of radiated electromagnetic energy, and arrange it by frequency. By looking at what is there (and what is not), we can derive a "fingerprint" of sorts that can be compared to known spectral displays. We can thus discover what is generating the given spectrum we are analyzing. This usually applies to visible light and frequencies close to that range of energies. In the world of radio, by applying spectrum analysis in given situations, we can discover where radiated energy from a source is "going" in the spectrum. For instance, a satellite launched by an "unfriendly" nation might be transmitting data across a range of frequencies using spread spectrum technology. By pointing a big antenna at it and looking at the range of emissions, we can see all the things it is transmitting across that range of frequencies. Then we can consider how the signals are being transmitted, and if they are in digital form, we turn on the big supercomputers and see if we can crunch the data to make it into something that makes sense.
Both of these are part of the electromagnetic spectrum. The main difference between the two is the wavelength and frequency. (Frequency multiplied by Wavelength always equals the Speed of Light, the constant abbreviated as "c". This is approximately equal to 186,000 miles per second or 300,000 km per second. If you know the wavelength and you want to find the frequency, divide "c" by the wavelength. )
its has a realtionship because you can see light and eye sight can be attracted to it.
less light intensity gives a better vision
All the electro-magnetic waves travel at the speed of light. Electromagnetic spectrum includes the following: * X-rays * Gamma rays * Ultraviolet rays * Infrared waves * Microwaves * Radio waves * Cosmic rays
Visible light is a small section in the electromagnetic spectrum.
Visible light and infrared light are the parts of the electromagnetic spectrum that can be seen with the eye.
They all are electromagnetic waves
Different wavelengths on the spectrum are seen as different colors within the visible light section of the spectrum.
Visible light is a small section in the electromagnetic spectrum.
Visible light and infrared light are the parts of the electromagnetic spectrum that can be seen with the eye.
Visible light falls between the wavelengths of 380 nm and 760 nm in the electromagnetic spectrum.
The band of the electromagnetic spectrum that has a wavelength between infrared and ultraviolet is the visible light spectrum. This is the portion of the electromagnetic spectrum that is visible to the human eye and includes colors such as red, green, and blue.
The part of the electromagnetic spectrum that we can see is called visible light. It is the range of electromagnetic radiation that the human eye is sensitive to, with wavelengths between approximately 400 to 700 nanometers.
Light falls within the electromagnetic spectrum as a form of electromagnetic radiation. It specifically falls between ultraviolet and infrared radiation, with visible light occupying the wavelengths of 400-700 nanometers.
Visible light is in the portion of the electromagnetic spectrum between infrared (IR) and ultraviolet (UV) light.
White light is a combination of all the colors in the visible spectrum, which includes red, orange, yellow, green, blue, and violet. It is found in the middle of the electromagnetic spectrum, between infrared and ultraviolet light.
