Verify that wave function
`(y=(2)/(x-3t)^(2)+1)`
is a solution to the linear wave equation, x and y are in centimetres.

Explanation

To verify that the wave function \( y = \frac{2}{(x - 3t)^2} + 1 \) is a solution to the linear wave equation, we will follow these steps:

### Step 1: Write down the wave equation
The linear wave equation in one dimension is given by:
\[ \frac{\partial^2 y}{\partial x^2} = \frac{1}{v^2} \frac{\partial^2 y}{\partial t^2} \]
where \( v \) is the wave velocity.
