What is the speed of an electromagnetic wave with a frequency of 100 mhz as it travels through a vacuum?
SCORPION-xisa [38]

Answer:

The speed of the wave with a frequency 100 mhz will be  3\times 10^{8}m/sec

And we know that speed of light is equal to 3\times 10^{8}m/sec

So the speed of the wave with a frequency 100 mhz will be  3\times 10^{8}m/sec
