Question

This graph is accurate because A) mechanical waves cannot travel through a medium. B) electromagnetic waves cannot travel through a vacuum. C) electromagnetic waves move faster than mechanical waves. D) mechanical waves move faster than electromagnetic waves.

Answer 1

Answer:

Option c

Explanation:

Electromagnetic waves are the waves which can travel in vacuum unlike mechanical waves which require a medium to travel. Electromagnetic waves have highest speed in vacuum. In fact, no thing can have speed greater than the speed of EM waves in vacuum. EM waves, thus move faster than the mechanical waves. EM waves carry energy by oscillations of magnetic and electric fields perpendicular to the direction of motion.

Answer 2

Answer:

IT would be C.electromagnetic waves move faster than mechanical waves.
