Red light of wavelength 645 nm falls on a single slit, which is located 1.10 m in front of a screen. You measure
the distance from the center of the bright central band to the
first dark band as 0.950 mm. (a) What is the angular
deviation to the first minimum? (b) What is the width of the
slit? (b) What is the angle measurement for the second order
minimum?
