Question

Which of these help create radio waves?

changing electric and magnetic fields applied at right angles

longitudinal waves traveling along the horizontal direction

compressions traveling along the vertical direction

transverse waves traveling at different speeds

Answer 1

the one that help create radio waves is :
Changing electric and magnetic fields applied at right angles

Radio waves are transverse wave, which means  that the oscillations occurring perpendicular to the direction of energy transfer

hope this helps
