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

A. Calculate the angle in degrees at which a 2.15 µm wide slit produces its first minimum for 410 nm violet light. Enter your result to the nearest 0.1°.
