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.

Which of these statements about the EM spectrum is false?
Most of the EM spectrum is visible light.
Where is wave located on the em spectrum?
all of the em spectrum is measured i waves
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).
How does the em spectrum effect what you see?
See:What_is_a_visible_spectrum
What to properties of EM waves change from one end of the EM spectrum to the other?
Wavelength and frequency :)
What are the types of waves in the electromagnetic spectrum?
All electromagnetic (EM) waves are in the EM spectrum. This is from "ELF" (3-30hz) through visible light (300Thz+), out past gamma rays. Any wave above DC that broadcasts into space is part of the EM spectrum.
Where is the uv rays located on the spectrum?
just beyond violet in the visible light section of the em spectrum
The range of electromagnetic waves placed in a certain order is called the?
Well there is the Electromagnetic (EM) spectrum. Visible light is the light that we can see and they are red, orange, yellow, green, blue, indigo, and violet. On the EM spectrum there is radio/ TV, microwaves, infrared, ultraviolet (UV), xrays,and gamma rays.
What member of the em spectrum has the highest frequecy?
Gamma rays
What are the waves in the EM spectrum?
Radio waves are the longest lengthwise.
Which band of em spectrum used in night sight?
infrared
What are the primary em spectrum colors?
Red, blue and green.
