What conclusion does the student most likely make based
on this data?

Light waves always travel the same speed; however, the
speed of sound is determined by the medium that it
travels through
O All sound waves always have the same energy, so the
temperature of the medium does not affect wave speed.
O Light needs to vibrate particles, so it travels fastest in
tightly packed solids, while sound does not need a
medium, so it travels fastest in a gas.
Tightly packed particles in solids slow down the light
waves, however, sound waves make particles bounce
into each other, so they travel faster in solids.
Which one?
