(a) Reflection of a pulse from a free boundary is really the superposition of two identical waves travelling in opposite direction. This can be shown as under.
In every 1/2 s, each pulse (one real moving towards right and one imaginary moving towards left) travels a distance of 1 cm, as the the wave speed is 2 cm/s.
