Question

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

Answer 1

Electromagnetic radiation does not require a medium to travel through. Instead, it can exist in the form of photons in the absence of a medium.

Answer 2

Answer: The correct answer is Option B.

Step-by-step 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.
