How do electromagnetic radiations differ?
Electromagnetic radiation is concerned with the movement of photons (individual, discrete 'packets' of light energy.) The frequency of electromagnetic radiation is directly proportional to its energy and inversely proportional to it's wavelength. Thus, a higher frequency will mean that the photons have a shorter wavelength and have more energy.Different frequencies, and therefore energies, of electromagnetic radiation will give it different properties. Because of this, the frequencies of electromagnetic radiation are divided into a spectrum based on the different properties of electromagnetic radiation of different frequencies. This spectrum goes from radio waves at the very low end to gamma rays at the other end.See the link at the bottom for a diagram of the Electromagnetic Spectrum.However, in the below image the word 'heat' is wrong. Between Infra-red and Radio waves are microwaves.Nuclear radiation is normally concerned with any form of radiation emitted as a result of radioactive decay, in which a large, unstable nucleus of an atom breaks down to form a more stable one.There are three types of nuclear radiation: alpha, beta, and gamma. Alpha decay is when an unstable nucleus emits an alpha particle which is composed of two protons and two neutrons; i.e. it is effectively a helium nucleus. Beta decay is when an unstable nucleus emits a beta particle (an electron), and gamma emission is when an unstable nucleus emits high energy electromagnetic radiation called gamma rays.
What is material properties to absorb electromagnetic?
That varies A LOT depending on the frequency of the wave. There are huge differences in things like absorption, between radio waves, visible light, gamma rays, etc.
Should electromagnetic radiation be avoided at all cost?
No mainly because it is impossible. The electromagnetic spectrum is everywhere visible light is a small part of it as are radio waves. It isn't a bad idea to avoid some of it X rays, ultraviolet light, microwaves etc. are potentially harmful hence the issue with cell phones high tension power cables etc.
What are three things you need to make an electromagnetic?
Three things you need to make an electromagnetic are a magnetic field, an electric current, and a conductor or coil of wire. When an electric current flows through the conductor, a magnetic field is created around it, resulting in an electromagnetic effect.
Why is radiation from earths surface and the atmosphere important to living things?
It is light that is important to life. The sun gives off a lot of electromagnetic radiation, and this radiation allows life on earth to flourish. Without sunlight, most life on earth would die, and the rest would be frozen solid in ice. It's that simple. Light, as you recall, is part of the electromagnetic spectrum; it's electromagnetic energy.
How is the electromagnetic spectrum useful?
Visible light, which lets humans and other animals see, is part of the electromagnetic spectrum. RF (radio frequency) waves are part of the electromagnetic spectrum. RF transmissions carry radio and television broadcasts. They have the lowest frequency. Microwaves are part of the electromagnetic spectrum. X-Rays are part of the electromagnetic spectrum and have the highest frequency..
What part of the electromagnetic spectrum does cholophyll reflect?
the electromagnetic spectrum is reflected by different things like TVs and glass
What is the entire range of energy waves that exist in the universe?
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.
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.
A frequency of 1GHz on a spectrum analyser corresponds to what frequency in the Ku band?
The Ku band of microwave frequencies ranges from 12 to 18 GHz. A frequency of 1GHz is not in the Ku band. There is no correspondence. Is the 1GHz setting on the spectrum analyzer a center frequency? Or is it one of the ends of the spectrum analyzed? Is it the width of the spectrum being analyzed? And if it is the latter, what is its center? Knowing these things will still not change the answer given, but may help to "sort out" a possible problem with the question the way it is written.

What is the purpose of the first radio telescope in the Philippines?
All Radio Telescopes form images of astronomical objects using a frequency of the electromagnetic spectrum (radio waves) that human eyes can not detect. This tells us things about these regions of space that we cannot learn in other ways.
Is light the same as electromagnetic radiation?
Yes, it is. Electromagnetic (EM) waves have frequency and amplitude (as well as polarity and a couple of other things), and because it has frequency, it can be distributed across a range of frequencies, or a spectrum - an electromagnetic spectrum. Light is a range of frequencies in what we call the optical or visible range. It is bounded on the lower end (lower frequency, lower energy, longer wavelength) by infrared (IR) light, and on the upper end (higher frequency, higher energy, shorter wavelength) by ultraviolet (UV) light.Yes. Light is also called a "electromagnetic wave"
Where on the electromagnetic spectrum do you find Am and FM waves?
There are no such things as 'AM' and 'FM' waves. When we take an electromagnetic wave, and force it to carry information by changing its amplitude according to some pattern related to the information, we operate on it with the process of 'AM'. Commercial radio stations that add sound information to their carrier waves in that way operate in the frequency band of 0.55 - 1.7 MHz (in the US). When we take an electromagnetic wave, and force it to carry information by changing its frequency according to some pattern related to the information, we operate on it with the process of 'FM'. Commercial radio stations that add sound and other information to their carrier waves in that way operate in the frequency band of 88 - 108 MHz (in the US).
What does ultraviolet rays and infrared rays have in common?
Infrared (IR) light, visible light and X-rays are all electromagnetic radiation, and the only difference is in the frequency (or wavelength) of the energy. They are listed here in the question in order of lower to higher frequency, and that means longer to shorter wavelength.
Is the frequency the same as the speed of the electromagnetic radiation?
No, the two things are quite difference. Frequency means how often a wave goes "up" and "down" - it is measured in cycles/second (hertz). Speed is measured in meters/second. The relationship is: speed = frequency x wavelength This relationship is valid for any wave. In the case of electromagnetic waves, the speed is approximately 300,000,000 m/s.
What is the relationship between the energy and wavelength of electromagnetic radiation?
Wavelength and frequency are inversely proportional. The higher the frequency, the shorter (lower) the wavelength. Energy is proportional to frequency, and higher frequency waves will have a higher energy. Mathematically, frequency = 1 divided by wavelength, or f = 1/λ Use the link below for more information, including a diagram or two to make things clearer.
