Try2:- (a) If A see 30 min in his clock that is coordinate time so proper time in B's frame should be: ∆t= 30 min, ∆t=∆t'/√(1-(v/c)^2) ∆t'=30*(√(1-(2/3)^2))=22.4min { And this must be the time when A's coordinate clock is at exactly the position where B is at that time... } But, how to...

Ques) 2 observers, A on Earth and B in rocket ship whose speed is 2x10(^8) m/s, both set their watches at 1:00 when ship is abreast of the earth. (a) When A's watch reads 1:30, he looks at B's watch through telescope, (b) When B's watch reads 1:30, he looks at A's watch through telescope...
