(a) In Figure 14.14, is the period of the clock according to observer \(\mathrm{B}\) greater than, equal to, or less than the period according to \(\mathrm{A}\) ?

(b) Does the period of the clock according to \(B\) increase, decrease, or stay the same if we increase \(v\) ?

Figure 14.14 Because the speed of light in vacuum is always co, the light signal in a light clock takes longer to reach the mirror according to an observer moving relative to the clock than to an observer at rest relative to the clock.
