`n` identical coherent waves each with the same initial phase arrive at a point with identical path length. The intensity produced at this point is `l_(1)`. If the waves are all incoherent, the intensity produced is `l_(2)`. The ratio `(l_(1))/(l_(2))` is

Two identical coherent waves, each of intensity 'I', are producing an interference pattern. Find the value of the resultant intensity at a point destructive interference.

Two identical coherent waves, each of intensity 'I', are producing an interference pattern. Find the value of the resultant intensity at a point constructive interference.

Two identical coherent waves, each of intensity I are producing an interference pattern. find the value of the resultant intensity at a point of constructive interference.

if three are N atoms in a source of laser light and each atom is emitting light with intensity l, then the total intensity produced by it is

Assertion: Two identical waves due to two coherent sources interfere at a point with a phase difference of (2pi)/3 , then the resultant intensity at this point is equal to the individual intensity of the sources. Reason: A phase difference of (2pi)/3 is equivalent to a path difference of lambda/3 .
