Explain why only a limited range of radio frequencies can be used to transmit signals from Earth to satellites

My guess is that radio waves can't be transmitted at the same frequency or they will mix up?

Yess thats true because if they are the same frequency as other radio broadcasts tehn they will interfere with each other!!

Also terrie, only certain wavelengths of radio waves are good because they can defract around objects easily !!! so anything higher menanig with a shorter wavelength will make it harder to defract round objects !!!!!

oh but to transmit radio waves from earth to satellites you would need ones with a high frequency / short wavelength so they pass through the ionosphere and diffract little right?

ohhh thank you so much! I didn't think of that hehe :)

Exactly but ususally instead of radio waves they prefer microwaves because they wont be defracted as much as radio waves ===> shorter wavelength means your coming closer to microwaves so instead they just use microwaves but the idea behind it is rightlike u said about high frequency and shorter wavelegnth etc etc
