a student observes that it is hard to hear music underwater in a pool. they state that the sound is always muffled. they conclude that the speed of sound in water must be slower than in air.

what would you say about the validity of this conclusion?

a)
the conclusion follows from the observation.

b)
the conclusion might be valid. but the information is not absolute proof.

c)
the conclusion is not valid. all sound waves travel at the same speed, not altitude.

d)
the conclusion is not valid. the speed of sound should be greater in liquids. muffling is not about the speed of the wave.

The correct answer would be the option D.

The provided conclusion is not right as the speed of sound is much faster in water as compared to the speed of sound in air.

It is because the particles in water are much closer than the particles in the air. Consequently, they transmit the vibrations at a faster rate and thus, sound travels faster.

In addition, the muffling is not associated with the speed of the sound wave in the water. It occurs because human ears are evolved to hear sound in air due to which we hear clear sound in air.
