Question

1. choose the best answer.

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.
gravitational forces bend electrical energy.
magnetic and electric waves travel perpendicular to each other in radiation.

Explanation:

Radio waves and light waves are electromagnetic waves. Electromagnetic waves are created by the oscillation of electric and magnetic fields. In electromagnetic radiation, magnetic and electric waves travel perpendicular to each other.

• The first option is incorrect because radio waves and light waves are not sound waves.
• The second option is incorrect as it does not accurately describe the creation of radio and light waves.
• The third option is incorrect as gravitational forces are not related to the creation of radio and light waves in this context.

Answer:

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