Explain to your friend, who is willing to accept that light moves at the same speed in any frame, why clocks on a passing train are not synchronized. If it helps, assume that Anna is at the middle of the train.

Expert Solution & Answer

To determine

To Explain: The clocks on a passing train are not synchronized.

Explanation of Solution

Introduction:

According to Einstein postulates of relativity i.e.

In inertial frames physical laws are valid.
Speed of light never changes relative to observers.

Let, t be the time read by A. From A’s perspective, if a light signal was sent from the end of the train by the clock and they read it to be t . Then signal sent from the end of the train will reach together to A after time t .

If someone is outside, then according to outsider’s perspective, signals must be started at different times in order to reach Aat the same time(as A is in motion). Then as per outsider’s perspective clock should read t at different times.That’s why clocks on passing train are not synchronized.

They obtained a positive photoresist, a used spin coater, a high energy light lamp for exposure and ordered a plastic transparency mask with a pattern on it to reduce cost. Upon trying this set up multiple times they find that the full resist gets developed, and they are unable to transfer the pattern onto the resist. Help them troubleshoot and find out why pattern of transfer has not been successful. 5. You are given a composite…
