Q. Light of wavelength 450 nm falls on a 0.48 mm wide slit and forms a diffraction pattern on a screen 1.1 m away.

(a) Find the position of the first dark band on each side of the central maximum.

(b) Find the width of the central maximum.

Q. Two vectors, r and s, lie in the xy plane. Their magnitudes are 4.50 and 7.25 units, respectively, and their directions are 320° and 85°, respectively, as measured counterclockwise from the positive x axis. What are the values of the products?
