| Exam 200-355 | Question id=2475 | RF Fundamentals |
What does RF determine?
| A. |
cycle pattern size | |
| B. |
how often a wave occurs | |
| C. |
signal size | |
| D. |
quantity of energy injected in a signal |
RF communication works by creating electromagnetic waves at a source and being able to pick up those electromagnetic waves at a particular destination. These electromagnetic waves travel through the air at near the speed of light. The wavelength of an electromagnetic signal is inversely proportional to the frequency; the higher the frequency, the shorter the wavelength.
