Light has been measured as traveling at 3×108 m/s in a vacuum. Which of the following also travels at the speed of light, and why?

A
Ultrasound waves in a vacuum travel at the speed of light because there is no matter to reduce their speed.

B
Radio waves in a vacuum travel at the speed of light because they are a type of electromagnetic radiation like light.

C
Electrons in a current carrying wire travel at the speed of light because they have very little mass.

D
Gas particles at the center of an atomic explosion travel at the speed of light because the explosion creates an extreme outward force.

Radio waves in a vacuum travel at the speed of light because they are a type of electromagnetic radiation like a light has been measured as traveling at 3×10^8 m/s in a vacuum.

Charged particles that are accelerating, like time-varying electric currents, are what produce radio waves. Radio and television signals are transmitted using radio waves, and microwaves used in radar and microwave ovens are also radio waves. Radio waves are emitted by a lot of celestial bodies, including pulsars. High RF exposure levels have the potential to heat biological tissue and raise body temperature. The body's inability to handle or remove the extra heat that could be generated by high RF exposure in humans could result in tissue damage.
