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?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 and one-quarter of a wavelengths.The path difference between the two waves should be four wavelengths.The path difference between the two waves should be one-half of a wavelength.The path difference between the two waves should be one-quarter of a wavelength.The path difference between the two waves should be two wavelengths.The path difference between the two waves should be one wavelength.

When two beams of coherent light travel different paths, arriving at point P. If the maximum destructive interference is to occur at point P , then the condition for it is that the path difference of two beams must be odd multiple of half wavelength. Symbolically

path difference = ( 2n+1 ) λ / 2

So path difference may be λ/2 , 3λ/ 2, 5λ/ 2 etc .

Hence right option is

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

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

What is Wavelength?

This can be defined as the distance between successive crests or troughs and the path difference is denoted below:

Path difference = ( 2n+1 ) λ / 2 which could be λ/2 , 3λ/ 2 etc.

Hence , the path difference between the two waves should be one-half of a wavelength
