1. Would yellow light or green light produce the wider two- slit interference pattern? 2. If light and sound are both wave phenomena, why can we hear sounds around a corner but cannot see around a corner? 3. Red light is used to form a two-slit interference pattern on a screen. As the two slits are moved farther apart, does the separation of the bright bands on the screen decrease, increase, or remain the same?

Conceptual Example: Light shines through a rectangular hole that is narrower in the vertical direction than the horizontal. Would you expect the light to diffract more in the vertical direction or in horizontal direction?

Why more slits yield sharper peaks?

Unformatted text preview: The ability of lens to produce distinct images of two point objects very close together is called the resolution of lens. 1. Why cant an ordinary microscope using visible light be used to observe individual molecules? 2. Is it better to use red light or blue light to minimize diffraction effects while photographing tiny objects through a microscope? Why? 3. Why are the diffraction effects of your eyes more important during the day than at night? The two images are just resolvable when the center of the diffraction disk of one is directly over the first minimum in the diffraction pattern of the other. Interference by Thin Film A beam of light reflected by a material whose index of refraction is greater than that of the material in which it is traveling, changes phase by cycle. Polarization 1. Can sound waves be polarized? 2. If all the labels had come off the sunglasses in the drug store, how could you tell which ones were polarized?...
