Couldnt figure this out

U have 2 identical clocks where a pulse of light goes from a light source (a), reflects off a mirror (b) and goes to the end (c)

A person is stationary wrt one clock and another clock is in a space ship moving, relative to the observer, in the direction v at velocity v

The clock in the space ship is shown at time t1, t2 and t3

Theory says the observer should see the clock in the space ship ticking slower than the clock at rest wrt the observer.

If the height of the clock is H and its length is L the observer will deduce the clock in the space ship ticks at 2H/c. The observer will deduce the stationary clock will tick at some time greater than 2H/c ...is that right?
