Please refer to part (b) of Figure 1 included with this quiz. Here, theta (the angle the incident ray makes with respect to the vertical) is 40.0 degrees. What is d (the distance between the ray emerging from the bottom of the glass and where the ray would have been if it had continued straight on with no glass to refract it)? 1.78 m 1.11 m 0.56 m 1.33 m

As shown below, light from a vacuum is incident on a shard of Shawtonium (a newly discovered compound). The backside of the shard is up against an unknown material. When the light strikes the backside of the shard, total internal reflection occurs. The light then emerges from the side of the shard and resumes traveling through a vacuum. The index of refraction of Shawtonium is 1.8. Determine 0₁ & 0₂. vacuum 0₁ = 0₂ = unknown 8₂ shard 71° 36° 01...

Light enters a container of liquid at an angle of 49° to the normal; the refracted beam makes an angle of 29° with the normal. Calculate the index of refraction of this liquid. Group of answer choices 1.96 1.44 1.56 1.78

In the above figure, theta (the angle the incident ray makes with respect to the vertical) is 26.0 degrees. What is d (the distance between the ray emerging from the bottom of the glass and where the ray would have been if it had continued straight on with no glass to refract it)?

The figure below shows a light ray traveling in a slab of sodium chloride surrounded by air. The ray is incident on the right surface at an angle of 55° with the normal and then reflects from points A, B, and C. (Select all that apply.) A ray travels within a rectangular slab that is surrounded by air. The ray starts at the top of the slab and is incident on the right side of the slab at point A, and makes an angle of 55° to the normal. The ray reflects internally down and to the left and is incident on the bottom of the slab at point B, whereupon it reflects internally up and to the left until it is incident on the left side of the slab at point C, where it again reflects internally, up and to the right. (a) At which of these points does part of the ray enter the air? (Select all that apply.) A B C (b) If the sodium chloride slab is surrounded by diamond, at which point does part of the ray enter the diamond? (Select all that apply.) A B C

A ray of light is passed through a ruby and it hits a surface in contact with air (n = 1.000) at an angle of 45° with respect to the normal.  Use the table below to determine happens when it hits           the surface? What is the critical angle?   The ray refracts into the air at an angle of 45° with respect to the normal. The ray reflects back into the ruby at an angle of 45° with respect to the normal. The ray refracts at an angle of 90° with respect to the normal, along the surface. The ray is absorbed in the air. None of the above.

Q1. A ray of light (ray a) in air (index of refraction=1) strikes a flat piece of glass at an angle of p0 = 84° with respect to the normal, as shown in the figure. The index of refraction of the glass is 1.5. What is the angle 0 between the reflected ray (ray b) and refracted ray (ray c) rays?

The figure below shows the path of a light beam through several slabs with different indices of refraction. (n4 = 1.01) 10% = n = 1.60 n = 1.40 n = 1.20 14 (a) If 01 35.0°, what is the angle 02 of the emerging beam? 63.12 X Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.º
