Question 2:

The path difference between the two waves

\[ y_{1}= a_{1} sin \left( \omega t -\frac{2\Pi x}{\lambda} \right) \]

and

\[ y_{2}= a_{2} cos \left( \omega t -\frac{2\Pi x}{\lambda} + \varphi \right) \]

is

\[ \frac{\lambda}{2\Pi}\phi \]
\[ \frac{\lambda}{2\Pi}(\phi +\frac{\Pi}{2}) \]
\[ \frac{\lambda}{2\Pi}(\phi - \frac{\Pi}{2}) \]
\[ \frac{2\Pi}{\lambda}\phi  \]
