What is the name for all electromagnetic waves that exist?
The Electromagnetic Spectrum.
Does brown light exist in the visible spectrum?
No, brown light does not exist in the visible spectrum. The visible spectrum ranges from violet to red, and brown is a combination of different colors that are not within this range.
What is the longest wavelength on a electromagnetic spectrum?
The electromagnetic waves with the longest wavelength are called radio waves.
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..
Does photoelectric effect take place below threshold frequency?
No, the photoelectric effect only occurs when the frequency of incident light is equal to or greater than the threshold frequency. Below the threshold frequency, photons do not possess enough energy to eject electrons from a material.
What is the chemical compound for pink?
This does not exist. The color pink, is a specific frequency range in the electromagnetic spectrum of visible light. Various chemical compounds exist which reflect this frequency range, and appear pink as a result.
What organization regulates the radio frequencies that CAP uses?
The organization that regulates radio frequencies in the United States, which would include those used by the Civil Air Patrol (CAP), is the Federal Communications Commission (FCC). The FCC manages the allocation of radio spectrum to ensure that communications are efficient and interference-free. In other countries, similar regulatory bodies exist to oversee radio frequency use.
Why intermediate frequency are constant?
The frequency spectrum has been distributed for various purposes. Otherwise, the people may use the frequencies of their choice & there will be wide range of interference. So, in order to ensure proper reception of signals, the standards have been fixed for the transmission of frequencies & also for the intermediate frequency because if the intermediate frequency is varied the overall frequency value will also vary. The intermediate frequency value should be so designed that it should not lie within the range of mixer stage. Otherwise, there is the production of noise signal due to the interference of mixer frequency & intermediate frequency. Also, the intermediate frequency should not be too high. Otherwise, it will reduce the selectivity of the receiver because of increase in bandwidth. Considering all these factors 455 khz is the most suitable intermediate frequency value for an AM receiver.
Objective in regulating the use of radio frequency spectrum?
The objective is to make it possible for the maximum number of users to co-exist within the existing radio spectrum, without interfering with each other. Radio spectrum is like land . . . no more of it is being manufactured.
What is the name for all electromagnetic waves that exist?
The Electromagnetic Spectrum.
Are radio waves the shiortest wavelength of all EM waves?
Radio waves have almost the lowest frequency of any electromagnetic wave, but as the frequency, f, is related to the wavelength, l , and the speed of light, c, by the equation:f=c/lthis means that they have one of the longest wavelengths of all electromagnetic waves.On most illustrations of the electromagnetic spectrum, you will see Radio waves shown as the lowest frequencies of all. In fact, there are lower frequencies called ELF (extremely low frequency) waves. The most commonly encountered ELF waves are those that result from 50/60Hz electricity power lines, with wavelengths of some 6000km.In principle, though, there is no reason to suppose that there is a longest possible wavelength wave on the electromagnetic spectrum - electromagnetic waves may exist that have wavelengths of the order of light years, for example.
A certain dog whistle operates at 23.5 kHz while another brand operates at an unknown frequency When they play together they have a frequency of 5000 Hz Estimate the operating frequency of Brand X?
Sum or difference - so 28.5 or 18.5 KHZ All three frequencies still exist, not just the sum or difference.
Does brown light exist in the visible spectrum?
No, brown light does not exist in the visible spectrum. The visible spectrum ranges from violet to red, and brown is a combination of different colors that are not within this range.
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.
Is the electromagnetic spectrum harmful?
Certain parts of it can be. High frequency waves such as X-rays, gamma rays, and ultraviolet light can cause radiation burns and cancer. At the same time, life could not exist without the electromagnetic spectrum. The sun heats the earth through electromagnetic waves, and the light that drives photosynthesis is also part of that spectrum. Visible light, which allows us to see, is in the same range.
Why does the North American grid use the 60 Hz frequency in electrical generation?
There is no reason to prefer one Hz frequency over the other. In places like Japan both 50 and 60Hz frequencies co-exist together. It is simply the way North America has used since the development of the electrical power grid and there is no reason to need to go to a 50Hz system.
Is it possible for life on the center of the earth to exist?
Since the center of the Earth is in the molted form, it can not support life. Thus, it is not possible for life to exist on the center of the Earth.
