Question

what creates radio waves and light waves?
friction created by the acceleration of electrical energy creates high frequency sound waves.
frictional forces ignite chemicals that then send out energy as waves.
magnetic and electric waves travel perpendicular to each other in radiation.
gravitational forces bend electrical energy.

Explanation:

Radio waves and light waves are electromagnetic waves. Electromagnetic waves are formed by the oscillation of electric and magnetic fields that are perpendicular to each other.

Answer:

Magnetic and electric waves travel perpendicular to each other in radiation.
