Question

Listening to your favorite radio station involves which area of physics?

a-) optics
b-) thermodynamics

Answer 1

If I'm not mistaken the answer would be c, vibrations and wave phenomena, because when sound waves hit your ear they go through it to your brain and your mind translates these vibrations to sound. I hope my answer helped you out.
