4.7 Exercise 14

Monochromatic light of wavelength 530 nm passes through a horizontal single slit of width $1.5 \mu \text{m}$ in an opaque plate. A screen of dimensions $2.0 \text{m} \times 2.0 \text{m}$ is 1.2 m away from the slit. (a) Which way is the diffraction pattern spread out on the screen? (b) What are the angles of the minima with respect to the center? (c) What are the angles of the maxima? (d) How wide is the central bright fringe on the screen? (e) How wide is the next bright fringe on the screen?
