What does make Electro Magnetive wave to propagate through empty space
working on Wireless Network , where RF signal is used , so i want to about basic of EM wave.
Electromagnetic waves propogate easily through substances with less density.
The speed of light through empty space or through air is fast, which is 186,000 miles/sec. The speed of light in water(which has a higher density) decreases to 140,000 miles/sec.
The velocity of light, which is the same as the velocity of other electromagnetic waves, is considered to be constant, at 186,000 miles/sec. second.
