The carrier could be light, radio waves, almost any of the wave energies in this spectrum that are not hazardous to life. When used to convey information they are called carriers because one or more characteristics of the wave are varied to encode the information.
One of the simplest forms of encoding or modulating a carrier is amplitude modulation which is used to make radio frequencies carry sound. The amplitude of the radio frequency signal is varied in step with the sound.
What else can I help you with?
Which of these statements about the EM spectrum is false?
Most of the EM spectrum is visible light.
What is the difference between carrier and band?
The carrier is the actual EM energy used for transmission. The band is a subset of a convenient (and arbitrary) human conception of the electromagnetic spectrum. It's analogous to a real pencil line (the carrier) drawn in an imaginary lane (the band) of an endless expanse of very real concrete (the electromagnetic spectrum).
What to properties of EM waves change from one end of the EM spectrum to the other?
Wavelength and frequency :)
What are the primary em spectrum colors?
The primary EM spectrum colors are red, green, and blue. These colors can be combined in different ways to create all the other colors we see in the visible spectrum.
Where is wave located on the em spectrum?
Waves are a broad category on the electromagnetic (EM) spectrum that includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. They differ from each other in terms of their wavelength and frequency.
What is the basis of arrangement of EM waves in the spectrum?
Electromagnetic (EM) waves are arranged in the spectrum based on their wavelength or frequency. From longest to shortest wavelength/frequency, the EM spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. This arrangement is important because each region of the spectrum has unique properties and interactions with matter.
What are the waves in the EM spectrum?
Radio waves are the longest lengthwise.
What member of the em spectrum has the highest frequecy?
Gamma rays
Is visible light a major part of the EM spectrum?
It is certainly a very important part, but it is not a major part; 'visible light' makes up only a tiny part of the EM spectrum.
What type of em wave comes from incandescent light bulbs?
Visible and infra red parts of the EM spectrum
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.
Differences between the groups in the EM spectrum?
Only their wavelengths are different.
