Answer :
Electromagnetic waves going through outer space has the greatest speed among all kind of waves.
Option B
Explanation:
Electromagnetic waves are the waves that can go through the vaccum of space. Electromagnetic waves are made by the vibration of an electric charge. This vibration makes a wave that has both an "electric and magnetic nature". An electromagnetic wave transfers energy through a vaccum at a speed of [tex]3.00 \times 10^{8} \mathrm{m} / \mathrm{s}[/tex](speed esteem ordinarily depicted by the sign c). The spread of an electromagnetic wave through a material medium happens at a net speed which is under [tex]3.00 \times 10^{8} \mathrm{m} / \mathrm{s}[/tex].
