Q. Assertion :Short wave bands are used for transmission of radio waves to a large distance Reason: Short waves are reflected by ionosphere

Q. Assertion: Long distance radio broadcasts use short wave bands.
Reason: The short waves are absorbed by the Earth but reflected by F layer in the ionosphere. After reflection, they reach the surface of the Earth back only at a large distance from the transmitter.

Who discovered the ultra short radio waves?
