In an experiment conducted using the Young's double-slit apparatus, the separation between the slits is 20 µm. A first-order constructive interference fringe appears at an angle of 2.5o from the zeroth order (central) fringe.

A. What wavelength of light is used in the experiment?

B. At what angle would the fourth-order (m = 4) bright fringe appear?

C. At what angle would the fourth-order (m=4) dark fringe appear?
