Why can television satellites, which broadcast information as electromagnetic radiation, send signals from the vacuum of space?
a) because electromagnetic radiation increases as the distance increases
b) because electromagnetic radiation does not need a medium to travel through
c) because space does not provide a medium that will block the satellite signals
d) because space is so vast that light waves can spread out to their full size and strength

The correct answer is Option B.

Explanation:

Electromagnetic waves are defined as the waves which have electrical and magnetic component associated with them. These waves are known as  transverse waves.

In these waves, particles of the medium travel perpendicular to the direction of the wave. These waves does not require any medium to travel through. They can travel through the vacuum.

Hence, the correct answer is Option B.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
