Following figure shows sources 
and 
that emits light of wavelength 
in all directions. The sources are exactly in phase and are separated by a distance equal to 
If we start at the indicated start point and travel along path 1 and 2, the interference produce a maxima all along
Text Solution
Verified by ExpertsThe correct answer is:
A
At any point along the path 1, path difference between the waves is 0.
Hence maxima is obtained all along the path 1.
At any point along the path 2, path difference is 1.5 λ λ which is odd multiple of 
so minima is obtained all along the path 2.
