Q1:

Light of wavelength mm is incident on double slits 0.100 mm apart. Calculate the angle that corresponds to the third-order maximum of the diffracted light.

Q2:

What is the highest-order maximum for 400 nm light falling on double slits separated by 25.0 μm?

Q3:

Two slits m apart are illuminated by light of wavelength 600 nm. What is the highest-order fringe in the interference pattern?
