When the students were on the Dance Stage, they were easily able to follow all of the dance moves.

Later, when the students were about a mile away from the Dance Stage, they could still see the lights flash and hear the music. But the music was no longer timed with the light flashes, which made it difficult to dance in time with the lights and music!

Which of the following describes why the sound was no longer timed with the light flashes when the students were a mile away from the light and sound source?



Because light waves travel much faster than sound waves, the light waves reached the students before the sound waves.

Answer:

Because light waves travel much faster than sound waves, the light waves reached the students before the sound waves.

Step-by-step explanation:

Light travels faster than sound. This is demonstrated by thunder and lightning during a storm. They occur at the same time. When the storm is farther away, the lightning comes much before the thunder. When the storm is very near, you hear the thunder at the same time or right after the lightning.
