Question

In a double-slit experiment, two beams of coherent light traveling different paths arrive on a screen some distance away. What is the path difference between the two waves corresponding to the third bright band out from the central bright band?

The path difference between the two waves is three wavelengths.
The path difference between the two waves is two wavelengths.
The path difference between the two waves is four wavelengths.
The path difference between the two waves is one-half of a wavelength.
The path difference between the two waves is one and one-half wavelengths.
The path difference between the two waves is one wavelength.

Answer 1

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?
