YDSE Problems III

Q. Two sources $S_{1}and{S}_2$ emitting light of wavelength 600 nm are placed a distance $1.0\times {10}^{-2}$ cm apart. A detector can be moved on the line $S_{1}P$ which is perpendicular to $S_1{S}_2.$ Locate the position of the farthest minimum detected.

1. $S_{1}P$=0 m
2. $S_{1}P$=Infinite
3. $S_{1}P$= 1.7 m
4. $S_{1}P$= 6 m
