At what frequency are waves reflected off the ionosphere?
Below 30 MHz
1 of 5
At what frequency are waves absorbed and scattered?
Above 30GHz
2 of 5
How does diffraction change when the wavelength is increased?
It happens easier
3 of 5
When do you get maximum diffraction?
When the size of the gap is equal to the wavelength
4 of 5
Why are dishes used when transmitting and recieving satellite signals?
The microwaves won't diffract much, as the dish is much larger than the wavelength of the microwaves
