Why the upper end of The electromagnetic spread spectrum is not used for communication?
Light waves are used for communication when ships use lamp signalling. This is used because it has a short range and the communications can not be detected by anyone else, so they are secure. Optical cables also use light waves to achieve very hgh data speeds.
Above light frequencies the EM radiation becomes risky to use and is used only for specialised purposes like x-rays and cancer treatments.

What are the highest- frequency and lowest -frequency parts of the EM spectrum?
The highest frequency is gamma rays And the lowest is radio waves
How does the width of the visible spectrum compare to the entire electromagnetic spectrum?
it is slap bang in the midde of the spectrum, with Ultra Violet light on one side, and Infra red on the other. In a vacuum it travels at the same speed as all of the others (the speed of light) UV has a shorter wavelength, and Infra red has a slightly longer one.
Why does an incandescent light bulb produce a continuous spectrum that seems to favor red?
Actually the peak of the radiation from an incandescent light bulb is in the near infrared, not the visible spectrum. The visible light that you see is the falling upper sideband of this: very strong in the red and declining until it is weak in the blue and violet end with a very small amount of radiation in the ultraviolet. The lower sideband extends across the infrared and into the far infrared. Well under a third of the emitted electromagnetic radiation of an incandescent light bulb is visible light, most is infrared.
What is electromagnetic radiation with long wavelengths called?
... is an inherently meaningless term; no matter how long a wavelength you name, I can choose one that's longer ("infinity" is not a real wavelength, and for any non-infinite number, there's always a larger one).
What structure links the upper and lower centers of the brain?
The brainstem is the structure that links the upper and lower centers of the brain. It controls basic functions like breathing and heart rate, and also serves as a pathway for communication between the brain and the rest of the body.
What part of the electromagnetic spectrum has the greatest frequency?
If by greatest frequency you mean highest frequency, we know that the upper end of the electromagnetic spectrum has the greatest frequency. This is the home to the gamma rays. They have the highest frequency, shortest wavelength, and the greatest energy.
What is the correct terms when describing the frequency range of 3 kHz to 300 GHz?
Electromagnetic Frequency (EMF) & Radio Frequency (RF)
What is the significance of upper sideband in the context of radio frequency communication?
Upper sideband in radio frequency communication is significant because it carries the majority of the information being transmitted. By transmitting only the upper sideband, the bandwidth required for communication is reduced, making the transmission more efficient. This is important for optimizing the use of limited frequency spectrum and ensuring clear and reliable communication.
What are the highest-frequency and the lowest-frequency parts of the em spectrum?
-- The lowest frequencies that we have a name for are what we call "radio" waves. -- The highest frequencies that we have a name for are what we call "gamma" rays. Although there is not upper or lower limit in the electromagnetic spectrum.
What comprise the upper end of the EM spectrum?
The upper end of the electromagnetic spectrum includes gamma rays, X-rays, and ultraviolet rays. These waves have higher frequencies and shorter wavelengths compared to visible light and are typically associated with high-energy interactions such as nuclear processes and particle acceleration.
What is the purpose of electromagnetic spectrum?
The electromagnetic spectrum is simply a way to display the range of electromagnetic energies in a manner that some associations can be discovered. Electromagnetic (EM) energy is composed of two waves, one electrostatic and one electromagnetic, that propagate at right angles to one another. Since we are looking at waves, it is natural to consider that they have different periods (the time it takes for one cycle to occur). We can then extend our thinking to consider the length of the wave, and also the frequency (the number of cycles per second) of the energy. Finally, we can consider the energy that is being propagated in the wave. If we spread out all the different frequencies on a chart or diagram with the lowest frequencies to the left and the highest frequencies to the right (as we usually do), we have a display of the electromagnetic spectrum. Radio waves will be on the left. They have the longest wavelength and the longest period, and also the lowest frequency. A lot of the spectrum is taken up by radio waves. Further to the right come microwaves, then the EM radiation a bit lower in frequency than visible light, which is the infrared region of the spectrum. The optical spectrum (visible light) is represented by the reds, oranges, yellows, etc., that we who are fortunate to be sighted can know. Beyond the violet visible light is the ultraviolet region, and then soft (lower energy) X-rays, and then the hard X-rays. Finally we find the gamma rays at the upper end of the spectrum. Looking at all of the diagram, which is a representation arranged to a useful purpose, we can discover a number of things about electromagnetic energy. The different spectra (radio, microwave, etc.) all have distinct characteristics that we can apply in daily life. Low frequency radio waves are used in submarine communication. (They penetrate water to a degree, and can actually travel in a curve around the world.) Microwaves make your cellular phone work, and they heat food in a microwave oven. We (most of us) are visual creatures, and visible light from the optical spectrum allows us to navigate our way about. At a medical clinic, hospital or dental office, an X-ray allows health professionals to quite easily see things that cannot be looked at well with other methods. There is a lot to learn, and a display of the electromagnetic spectrum opens a door to understanding this type of energy.
Do gamma rays have a higher frequency than x rays?
Generally speaking, it is gamma rays that have a higher frequency (and energy) than X-rays. The upper end of the X-ray spectrum and the lower end of the gamma ray spectrum enjoy a bit of overlap, but the X-ray does not have a higher frequency than the gamma ray.
What on the electromagnetic spectrum has the highest frequency?
The visible spectrum : - red, orange, yellow, green, blue, violet. The blue end of the spectrum has a shorter wavelength, higher frequency and more energy than the red end of the spectrum. Thus violet light has the highest frequency and most energy.
