TIME DILATION The following problem shows the fact that different observers in different reference frames will measure different time intervals for a two events. Consider a trainbox moving with constant speed v as shown below. One observer is at point O inside the trainbox holding a laser and a second observer is at point O fixed on the ground. At some instant in time the laser emits a light pulse (event1) and travels toward a fixed mirror on top. The light pulse is reflected and then arrives at the laser (event 2). We would like to measure the time interval between these two events as measured relative to both observers. Time Measure in O 2 d t c ∆ = Time measured in O Relative to observer in O by the time the light pulse reaches the mirror and then back to the laser, the trainbox and mirror will have moved a distance vΔt. The path observed by the observer in O is shown in figure (b). Thus, the light pulse will travel further relative to the observer in O and the time interval Δt measured
