Standing wave Waves which appear to be vibrating vertically without traveling horizontally. Created from waves with identical frequency and amplitude interfering with one another while traveling in opposite directions.
Node Positions on a standing wave where the wave stays in a fixed position over time because of destructive interference.
Antinode Positions on a standing wave where the wave vibrates with maximum amplitude.
Fundamental frequency Lowest frequency of a standing wave that has the fewest number of nodes and antinodes.
Harmonic A standing wave that is a positive integer multiple of the fundamental frequency.

Generally from kinematic equation we have that
before the jump the persons initial velocity is u = 0 m/s
So
=>
