Which Mode Is Used for Short Wave Broadcast Service

The oscillating electric field of electromagnetic wave changes the velocity of the electrons in the ionosphere which changes the effective dielectric constant and hence. Which Mode Of Propagation Is Used By Short Wave Broadcast Services Having Frequency Range From A Few Mhz Upto 30 Mhz Explain Diagrammatically How Long Distance Communication Can Be Achieved By When the radiowaves from the transmitting antenna reach the receiving antenna either directly or after reflection from the ground or in troposphere the wave propagation is called space wave. .
