Question

A spaceship emits flashes of light every 6 minutes for one hour. If the receiver sees these light flashes at 3 minute intervals, how much time in minutes will occur between the first and the last light flash in the frame of reference of the receiver? Do NOT include labels.​

Answer 1

In the frame of reference of the receiver, the time between the first and the last light flash is 27 minutes.

Step-by-step explanation:

In the frame of reference of the receiver, the spaceship emits flashes of light every 3 minutes because the receiver sees these light flashes at 3 minute intervals.

The time between the first and the last light flash in the frame of reference of the receiver can be calculated as follows:

1. One hour is equal to 60 minutes.
2. The spaceship emits flashes of light every 6 minutes for one hour, so the total number of light flashes emitted is 60/6 = 10.
3. Since the receiver sees these light flashes at 3 minute intervals, the total time between the first and the last light flash in the frame of reference of the receiver is (10 - 1) * 3 = 27 minutes.
