Question

In which case is the speed of laser light the slowest relative to the observer? a person walking in the street and who sees laser light emitted from a low‑speed car that moves in the same direction as the person a student sitting in the classroom and who see laser light from the pointer used by the instructor laser light emitted from a high‑speed aircraft and detected by another high‑speed aircraft traveling in the opposite direction a person who sees laser light passing through a bucket full of water it is the same for all of the above

Answer 1

Answer:

a person who sees laser light passing through a bucket full of water.

Explanation:

According to relativity, the speed of light is the same irrespective of the relative speed between the source, and the observer. The only exception is when light travel from a less dense medium to a denser medium as in air into the bucket full of water. So the speed of light is slowest relative to the observer in the laser that passes through the bucket of water.
