Atransverse wave is described by the function y(x, t)=2.3cos(4.7x+12t−π/2), where distance is measured in meters and time in seconds. how long does it take for the point at x = 0 to move from a displacement of 0 m to a displacement of 1.1 m?

Explanation:

Given:

Now putting initial condition in the wave equation:

encountering the first occurrence:

.........................(1)

Now putting final condition in the wave equation:

encountering the first occurrence:

.........................(2)

Now time elapsed:

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
