With wave terminology, a Cycle is when?
A cycle is when a single oscillation of a waveform occurs from zero to a positive value.
Frequency is the
number of cycles that occurred during a period and is measured in HZ
What is a wavelength
The distance between two repeating patterns in waveform
What is amplitude
The intensity of a waveform is identified by the maximum height of the waveform
What are some common frequency bands
2.4 GHZ
5 GHZ
6 GHZ
What happens to the wavelength as the frequency increases?
Wavelength decreases
What are some benefits of a lower frequency wavelength?
Can pass through walls more easily
Experience less attenuation
Describe the pros and cons of higher frequency
Higher frequency can support higher bandwidth
Travels a shorter distance
