What conclusion does the student most likely make based on this data?
Answer
A
Light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through.
B
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.
C
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.
D
All sound waves always have the same energy, so the temperature of the medium does not affect wave speed.
