help please? :)

hey peoples

 

would someone please be able to help me a bit with this relativity problem?

 

Cheers

i know the period should be the same as a clock whose length is perpendicular to the motion but i just can't get the equation out...

[Sarahisme]

the time between the emission and reflection events relative to the observer ....i got:

 

L/{gamma} + vt = ct

 

therefore

 

t = L/({gamma}*(c-v))

[Sarahisme]

and between reflection and return (relative to the observer):

 

t = L/({gamma}*(c+v))

[Sarahisme]

and for the period of the clock (relative to the observer):

 

T = 2Lc/({gamma}*(c^{2}-v^{2}))

 

but then this does equal what its meant to.... (i.e. T = 2L{gamma}/c )

[Sarahisme]

ok then...nobody reply...thats fine, even to tell me i'm stupid would be nice!

[Sarahisme]

lol well then !

Whoa! I just noticed this now, and I have been checking in daily lately.

 

I can hardly read your jpg. Can you post a larger version?

[Sarahisme]

This one appeared while I was away - missed it.

 

It looks correct.
