jht ray undergoes multiple reflections along a glass corridor where the walls are parallel or perpendicular to one another (Figure 2). If Air the angle of incidence is 30°, draw all the reflections and refractions and determine the angles along the path. a Figure 2

A goldfish is swimming inside a spherical bowl of water having an index of refraction n = 1.333. Suppose the goldfish is p = 10.7 cm from the wall of a bowl of radius |R| = 19.2 cm, as in the figure below. Neglecting the refraction of light caused by the wall of the bowl, determine the apparent distance of the goldfish from the wall according to an observer outside the bowl.cm behind the glass

Your boss calls you in his office and hands you the plot shown below. The plot represent data of reflection coefficient for an EM-wave at oblique incidence. It includes the index of refraction of the second medium (n2) and also an angle that your boss does not understand what it is. Your boss tells you that in 30 min, the customer will call back and wants the following information: 1. What polarization has been used to obtain the data 2. What is the index of refraction of the first medium and whether or not is an external or internal reflection. 3. What does the number right above the x-axis represent. 1.5 n;= 3 0.5 41.42 -0.5 10 20 30 40 50 60 70 80 90 Angle of incidence Reflection Coefficients

A plastic light pipe has an index of refraction of 1.51. For total internal reflection, what is the minimum angle of incidence if the pipe is in the following media? (a) air (b) water O O

Light is incident from medium I to medisum 2 at Brewster's angle equal to 55.4, and transmitted angle is 34.6, the permeability of medium 2 is 34. 1. Caleulate refractive indices for medium land medium 2 2. Calculate the reflection coefficient for spolarined. 3. Reflection coefficient for p- polarized.

When light reflects off horizontal surfaces some of the vertical components of the electric fields are absorbed while the horizontal components are reflected. In order for a polarizing set of sunglasses to be effective the glasses must be aligned so that it will block the components of the electric fields. horizontal vertical spherical elliptical
