BTwo slits separated by a distance of d = 0.12 mm are located at a distance of D = 670 mm from a screen. The screen is oriented parallel to the plane of the slits. The slits are illuminated by light of wavelength λ = 525 nm. The interference pattern shows a peak at the centre of the screen (m = 0) and then alternating minima and maxima.
A- What is the path difference between the waves from the two slits at the first (m = 1) maximum on the screen?
B- What is the path difference between the waves from the two slits at the first (m = 0) minimum on the screen?
