The light signal takes t1 time to reach from Y to O as (c−v) OX and the time t2 taken by the light signal from X to O is (c+v) . [c is the velocity of light in all direction. 5 The Relativistic Concept of Space and Time 19 One can note that t1 = OX OY = = t2 , as c + v = c − v , O X = OY (c − v) (c + v) Therefore, time is not absolute. e. t1 = t2 . In other words, every reference frame has its own particular time. Therefore, concept of absolute time was ruled out by Einstein. The space coordinate is transformed due to Galilean Transformation as x 1 = x − vt.
Therefore, α t1 = 1− f 2 c2 c2 etc. t If N0 is the initial flux and N is the flux after time t, then we have N = N0 e− τ , τ being the mean lifetime. t Here, N = e−β N0 , therefore e−β N0 = N0 e− τ =⇒ t = βτ = β t 1 = √ αβ 2 . 1− f Hence, the distance traversed by the beam before the flux of mesons beam is reduced to e−β times the initial flux is d = t × f c etc. 3 At what speed should a clock be moved, so that it may appear to loose α seconds in each minute. Hint: If the clock is to loose α seconds in each minute, then the moving clock with velocity v records 60 − α s for each 60 s recorded by stationary clock.
Suppose that a light signal from a light source emits a pulse at the common origin of S and S 1 at time t = t 1 = 0 and the observers in each system measures the speed of the propagate of light wave. e. 35) in Eqs. 37) v2 c2 Thus Eqs. 37) give the required Lorentz Transformations. 3 The General Lorentz Transformations Now, we search the Lorentz Transformations for an arbitrary direction of the relative → → r of a velocity − v between S and S1 frames. Let us consider the position vector − → particle separate into two components, one parallel and another perpendicular to − v.
