Homework Statement
You are finding it a challenge to climb from one boat up onto a higher boat in heavy waves.
If the climb varies from 2.1 m to 4.5m , what is the amplitude of the wave? Assume the centers of the two boats are a half wavelength apart.
Homework Equations
just used simple arithmatic
The Attempt at a Solution
so since the starting point will be 2.1 m, i assumed that to get the amplitude i would only have to subtract that from the height of the higher boat. so 4.5 - 2.1 = 2.4
This answer is incorrect. Please explain why.
