Chromatic aberration comes from the fact that different wavelengths of light travel at different speeds through the material of the lens; that is, they have different indices of refraction, a property known as dispersion. This means that a lens, in effect, has different focal lengths for different wavelengths of light. Consider a lens made to the following specifications: focal length for red light fred=19.57cm, focal length for blue light fblue=18.87cm. Part A Consider an object 5.000cm tall placed a distance...

In the figure, a light ray enters a glass slab at point
A at incident angle θ1 =
60.9o and then undergoes total internal reflection at
point B. What minimum value for the index of refraction of
the glass can be inferred from this information? Assume that the
index of refraction of air under standard temperature (0°C) and
pressure (1 atm) is 1.00029.

Suppose that white light strikes a surface of flint glass at an angle of 60 degrees. The index of refraction of this dense glass for red light is 1.710, for green light is 1.723, and for blue light is 1.735. What is the order of colors you would see in the refracted light? In the reflected light? From the surface up -- a.) Refraction: red green blue b.) Refraction: blue green red c.) Refraction: red green blue d.) Refraction: blue...
