Answer 1

Answer:

D: In a vacuum

Explanation:

i took the test

Answer 2

Answer:

in a vacuum

Explanation:

In physics, a transverse wave is a moving wave whose oscillations are perpendicular to the direction of the wave or path of propagation. In a transverse wave, the particles are displaced perpendicular to the direction the wave travels. Electromagnetic waves are transverse waves. They require no material medium for propagation and travel fastest in a vacuum.

Sound waves are longitudinal waves. In longitudinal waves, the vibrations are parallel to the direction of wave travel. Sound waves do not travel through vacuum because they require a material medium (air) for propagation. A vacuum has no air hence sound waves do not travel through a vacuum.
