Yes, of course. That was very careless of me.
Can you let me know whether my previous analysis was right and what the correct answer would be so that I can try to work towards it?
Thanks again for your help.
Hello and thanks for the very helpful discussion which has clarified the ideas in my mind.
I'm still having difficulty with getting the right answers out though. According to 'French' they are +0.27 and -0.34. The light left them before t=0 and took the time difference to arrive at the...
Thanks for the answers.
I think what I need to do is work out what additional length will be added to the -x direction to allow for the finite speed of light and what length needs to be taken off the +x direction? Not sure how I should do that though?
Am I right in thinking that the length on...
No. My answer was for where in the observer's frame of reference is the stick. I calcualted +/-/0.3m. Now I have to think about the position on the photograph. I suspect that you have to take into account not only the contraction but also the finite speed of light?
Thanks for answering Fewmet.
The first part of the question was where in the observer's frame are the end points of the meter stick and I have successfully calculated that to be +/- 0.3m. Now I'm stuck on the next bit which I've posted. Just not sure how to tackle this next bit.
A meter stick, pointing in the x-direction moves along the x-axis with speed v=0.8c, with its midpoint passing through the origin at time t=0. A stationary observer situated at the origin takes a photograph of the stick at time t=0. At what poisition does the photograph show...
This has got to be easy but I can't find the answer anywhere. How can I use 'plot' where the x axis does not include the end points 0 or 5? All the examples I see are things like x=[0:0.1:5].
Thanks in advance.
