5. Figure 3 gives the lateral magnification m of an object versus the object distance p from a spherical mirror as the object is moved along the mirror's central axis through a range of values for p. The horizontal scale is set by p, 10.0 cm. What is the magnification of the object when the object is 21 cm from the mirror? (15 points) 6. In Figure 4, two light rays go through different paths by reflecting...
In the figure, sound waves A and B, both of
wavelength λ, are initially in phase and traveling
rightward, as indicated by the two rays. Wave A is
reflected from four surfaces but ends up traveling in its original
direction. Wave B ends in that direction after reflecting
from two surfaces. Let distance L in the figure be
expressed as a multiple q of λ: L =
qλ. What are the (a) smallest and
(b) second smallest values of q...
In the figure, assume two waves
of light in air, of wavelength 556 nm, are initially in phase. One
travels through a glass layer of index of refraction
n1 = 1.57 and thickness L. The other
travels through an equally thick plastic layer of index of
refraction n2 = 1.34. What is the smallest
value L in meters should have if the waves are to end up
with a phase difference of 4.96 rad?
In a double-slit experiment, two beams of coherent light traveling different paths arrive on a screen some distance away. What is the path difference between the two waves corresponding to the third bright band out from the central bright band?

A light ray in air (n= 1) is incident on a thin film of oil (noil = 1.60) floating on top of water (nwater = 1.33), as shown below. The wavelength of the incident light in air is Aair = 640 nm. The oil layer has a thickness t = 0.5 um. The ray is assumed to be incident practically along the normal. That is, we won't be worried about angles of reflection or refraction when doing this problem. However,...
eG GO In Fig. 35-51a, the waves along rays 1 and 2 are initially in whase with the same wavelength 1 in air. Ray 2 goes through a ma- mial with length L and index of refraction n. The rays are then reflected by mirrors to a common point P on a screen. Suppose that we can vary n from n = 1.0 to n = 2.5. Suppose also that, from n = 1.0 to n = ns = 1.5,...
Screen 84 GO In Figure 35-50, two isotropic point sources S, and S, emit light in phase at wavelength 1 and at the same amplitude. The sources are separated by distance d = 6.001 on an x axis. A viewing screen is at distance D = 20.0, from S, and par- -d-to- allel to the y axis. The figure shows two rays reaching point P on the screen, at height yp. (a) At what value of yp do the rays...
An important experimental device that uses interference is the Michelson interferometer. Michelson interferometers are used to make precise measurements of wavelengths and of very small distances. A Michelson interferometer takes monochromatic light from a single source and divides it into two waves that follow different paths. Interference occurs when the two light waves are recombined. The figure below shows the principal components of a Michelson interferometer. A ray of light from a monochromatic source A strikes the beam splitter C,...
