Two slits are illuminated by a 536 nm light.The angle between the zeroth-order bright band at the center of the screen and the fourth-order bright band is 16.1 degrees. If the screen is 176 cm from the double-slit, how far apart is this bright band from the
central peak? Answer in units of cm.

What is the distance between the two slits? Answer in units of mm.
