Question light waves with two different wavelengths 632 nm, Ask an Expert

Academics

Question: Light waves with two different wavelengths, 632 nm and 474 nm, pass simultaneously through a single slit whose width is 4.22 × 10^-5 m and strike a screen 1.40 m from the slit. Two diffraction patterns are formed on the screen.

Part A- What is the distance (in cm) between the common center of the diffraction patterns and the first occurrence of the spot where a dark fringe from one pattern falls on top of a dark fringe from the other pattern?

Please show complete calculation Thanks!
