Well i said i wanted it to be a clock with very accurate frequensy, so

i expected to get an ***accurate*** clock with very high frequensy

that run in perfect sync with a neighbouring twinclock, i wanted the

frequensy of that clock in hz.

You always missunderstand things.

Simply count a unit oftimeas the bullet passes

each graduation on the ruler.

That is not a clock Sue..... not by a stretch

2. At what distance would those two clocks (if equipped with sensors)

measure the smallest photon emission to pass sensors *at same moment*.

You will have to catch some photons first so we

can design the sensors.

Your ability to missunderstand every question is amazing

3 Would this *same moment* be a number denoting the spatial extension

of the photon or simply a lack of the clocks to measure the process

with enough accuracy?

4. This i probably can calculate with the above given, but what length

of lightpath can the best clocks measure. The lightpath during a

second is 300 000 km, how long would the lightpath of the smallest

*distinctmeasurable*timeunit be.

<< where epsilon_0 and mu_0 are physical constants which

can be evaluated by performing two simple experiments

which involve measuring the force of attraction between

two fixed charges and two fixed parallel current carrying

wires. According to the relativity principle, these experiments

must yield the same values for epsilon_0 and mu_0 in all

inertial frames. Thus, the speed of light must be the

same in all inertial frames. >>http://farside.ph.utexas.edu/teaching/em/lectures/node108.html

Sue...

You did not answer 1,2,3 or 4 try again Sue, i find the answers to

these questions interesting
