As the width of the slit producing a single-slit diffraction pattern is reduced, how will the diffraction pattern produce change?
As the slit width is reduced, more diffraction is observed.

Using the information given in the preceding question, explain why sunsets are red.
(a) Show that a 30,000-line-per-centimeter grating will not produce a maximum for visible light. (b) What is the longest wavelength for which it does produce a first-order maximum? (c) What is the greatest number of lines per centimeter a diffraction grating can have and produce a complete second-order spectrum for visible light?
Suppose a feather appears green but has no green pigment. Explain in terms of diffraction.
What are the advantages of a diffraction grating over a prism in dispersing light for spectral analysis?
(a) What is the minimum angular spread of a \(633 - nm\) wavelength \({\rm{He - Ne}}\) laser beam that is originally \(1.00{\rm{ }}mm\) in diameter?
(b) If this laser is aimed at a mountain cliff \(15.0{\rm{ }}km\) away, how big will the illuminated spot be?
(c) How big a spot would be illuminated on the Moon, neglecting atmospheric effects? (This might be done to hit a corner reflector to measure the round-trip time and, hence, distance.) Explicitly show how you follow the steps in Problem-Solving Strategies for Wave Optics.
