Ch 24 rq prelecture concept question 24.01 1 of 5 constants part a two beams of coherent light travel different paths, arriving at point p. if the maximum destructive interference is to occur at point p, what should be the path difference between the two waves?

The path difference between the two waves should be one-half of a wavelength.

Explanation:

For the destructive interference to form at point P the path difference between the two waves should be

=

where n can be any integer starting from  0,1,2....

therefore we can say that

If the maximum destructive interference is to occur at point P, The path difference between the two waves should be one-half of a wavelength.

i took very good i wish you luck! i hope it .
