sound is a longitudinal wave
sound can be reflected and refracted like light
sound travels through a vacuum

The selected answer is wrong:
d correct option is C ..sound won't travel through vacuum , they ain't electromagnetic
Pls review this question the correct ans is C.
Like you said its longitudinal which means is a mechanical wave and all mechanical wave require medium for their propagation.
Therefore sound does not travel in vacuum.
Moreover speed of sound varies as thus, as regard to the option you chose
Solid =fastest
Liquid = faster
Gas = fast
The selected answer is wrong:
see ba ah dont have time to start checking books but think of a long steel rod about 400m when hit by another iron vibrations move faster than when air is being pased through it
SOUND CANNOT TRAVEL THROUGH A VACUUM BECAUSE IT IS A MECHANICAL WAVE AND MECHANICAL WAVES CANNOT TRAVEL THROUGH A VACUUM
The answer is C as sound as a vacuum doesn't have air molecules to transport the waves of sound.
MySchool the anwer is C. Sound is a mechanical wave. This means it requires a material medium for its propagation and thus cannot travel through empty space (vacuum)
