Asked by son

A teacher is standing 100 feet away with two students. When the teacher says now, 1 student turns on a flashlight, and another claps two wooden blocks together. The other students, who were standing 100 feet away, stated they saw the light 2 seconds before they heard the blocks. Why did this phenomenon happen?
Group of answer choices

Light travels faster in air than sound becuase air is not dense.

The light had more power so it moved faster. If the student hit the blocks harder the sound would win.

Light travels faster in air than sound becuase sound does not travel in the air..

The sound traveled faster, but the air absorbed the sound.

Correct choice: "Light travels faster in air than sound..."

Reason: Light moves at ~3×10^8 m/s, while sound in air is only ~343 m/s, so you see the flash essentially instantly but the clap takes much longer to reach you. (The other choices are wrong: light power doesn't change its speed, sound does travel through air, and air absorption would weaken sound but not make it arrive later than light in the way suggested.)
