A light ray is incident on an interface between materials 1 and 2. The light ray starts in medium 1, and has incident angle θi when it strikes the surface. The light ray refracts and continues on in medium 2, bending away from the normal.
(a) Draw the path of the light ray. Label in your picture θi .
(b) What is bigger, n1 or n2? Explain using Snell’s law.

To practice Tactics Box 18.1 Analyzing refraction. If a ray refracts between medium 1 and medium 2, having indices of refraction n1 and n2, the ray angles θ1 and θ2 in the two media are related by Snell's law, n1sinθ1=n2sinθ2. This law becomes a central idea in a procedure for analyzing refraction problems, as explained in the following Tactics Box. Draw a ray diagram. Represent the light beam with one ray. Draw a line normal to the boundary. Do this...

In thin film interference, an (a) incident wave reflects off of the front interface of the thin film and (b) refracts into the thin film.This refracted wave then (c) reflects off of the back interface of the thin film yet also (d) transmits through the film.This reflected wave then (e) refracts back through the front interface of the thin film in order to interfere with the wave that initially reflected off of the front interface.Apply the Fresnel equations that we...

When a light ray travels from a more dense medium to a less dense medium and the light ray intercepts the interface at some angle, the light ray will be deviated away from the normal to the interface. When the angle of the incident light ray is equal or greater than some critical angle , the light ray will be bent away from the normal unit the angle of refraction becomes 90, and total internal reflection occurs. The critical angle, , for two...

An incident coherent light ray strikes the interface between two different media with indices of refraction n1 and n2 (see figure below). Part of the ray gets reflected, and part of the ray gets refracted. Based on the information shown in the figure, which of the following is true? Let v1 and v2 be the speed of light in media 1 and 2, respectively. v1 < v2 v1 = v2 The reflected ray undergoes no phase shift relative to the...

In reflection and refraction of light, all angles are traditionally defined with respect to the perpendicular to the surface/interface at which the light is incident. When a ray of light travels from medium1 (whose refractive index is n1) to medium2 (whose refractive index is n2), it does the following: Bends further away from the perpendicular to the surface/interface if n1 > n2. Bends toward the perpendicular to the surface/interface if n1 > n2. Continues without changing its path (undeflected) even...
