Question

Ocean waves of wavelength 22 m are moving directly toward a concrete barrier wall at 4.6 m/s . The waves reflect from the wall, and the incoming and reflected waves overlap to make a lovely standing wave with an antinode at the wall. (Such waves are a common occurrence in certain places.) A kayaker is bobbing up and down with the water at the first antinode out from the wall.

Required:
a. How far from the wall is she?
b. What is the period of her up-and-down motion?

a)

b)

Explanation:

From the question we are told that:

Wavelength

Velocity

a)

Generally the equation for distance between her and the wall d is mathematically given by

Since

The First Anti node distance is

Therefore

b)

Generally the equation for her up-and-down motion is mathematically given by
