At t = 0 the end you are oscillating is at its maximum positive displacement and is instantaneously at rest. write an equation for the displacement as a function of time at a point 2.50 m from that end. assume that no wave bounces back from the other end. express your answer in millimeters in terms of t.

The equation of displacement is .

Explanation:

Given that,

Distance = 2.50 m

We need to calculate the equation of wave

Using general equation of wave

....(I)

Where, A = amplitude

t = time

x = displacement

= phase difference

Put the value in the equation

At t = 0, x = 0, y =A

From equation (I)

Hence, The equation of displacement is .
