What is dispersion?
A) the reflection of colors off the surface of a bright-colored translucent object, like a jewel
B) the separation of light into different colors because of how different colors of light refract differently
C) the refraction of light as it passes from air into water
D)the separation of colors of light because their waves superpose
E) the combination of a spectrum of colored lights into white light
ANSWER
B) the separation of light into different colors because of how different colors of light refract differently

"Dispersion" describes ____________, and happens when substances ____________. -the reflection of light rays from a surface (1st blank) -the bending of light rays across a boundary (1st blank) -the separation of light into different colors (1st blank) -the focusing of light to a point (1st blank) -have a high index of refraction (2nd blank) -have an index of refraction that depends on frequency (2nd blank) -are very reflective (2nd blank) -have a large focal length (2nd blank)
The Ocrit angle is= 24.09 degrees
A beam of white light is incident on the surface of a diamond at an angle 02. (Figure 1) The index of refraction actually depends on the light's wavelength, so the different colors that comprise white light will spread out as they pass through the diamond (like in a prism). The index of refraction in diamond is nblue = 2.450 for blue light while the indices of refraction for the lower frequency colors are...
are these right? im confused.

corrective Lenses
(@) Spectacles are often coated to reduce reflection. The plastic of the lens has a very thin coating of some other material with different refractive index (as shown in the figure). 11 T2 Air ni Coating TLV n2 Lens n3 Figure - cross section showing three parallel layers of material (air, coating and the lens), with a light ray incident on the coating. The ray is partially reflected at the air/coating interface; the reflected ray Ti is shown....
Note: This test contains ten questions from chapter 19 to chapter 27. For full credit, you should show all the steps of your numerical answers. No credit would be earned for just circling the right answers. Chapter 19 - Electric Potential and Electric Potential Energy 1. Two point charges are of + 7 uC and - 4 C are held at the corners of a rectangle as shown. The lengths of the sides of rectangle are 0.15 m, and 0.05...
