A wave travelling along X-axis is given by
`y=2(mm) sin (3t-6x+pi//4)`
where x is in centimetres and t in second. Write the phases and, hence, the find the phase difference between them at t=0 for two points on X-axis, `x=x_(1)=pi//3` cm and `x=x_(2)=pi//2` cm.

Explanation

To solve the problem step by step, we will follow these instructions:

1. **Identify the wave equation**: The wave is given by the equation:
\[ y = 2 \sin(3t - 6x + \frac{\pi}{4}) \]
Here, \(x\) is in centimeters and \(t\) is in seconds.
