Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Question

c) A grating has exactly 8000 slits uniformly spaced over 2.54 cm and is illuminated by light
from a mercury vapor discharge lamp. Compute the expected angle for the third order
maximum of the green line (λ = 546 nm)?
