Question: 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

1) $\frac{\lambda }{2\pi }\varphi $

2) $\frac{\lambda }{2\pi }\left( \varphi +\frac{\pi }{2} \right)$
