An optical fiber consists of a core made of flint glass (? core = 1.55) surrounded by a cladding made of crown glass (? cladding= 1.28). A ray of light in air enters the fiber at an angle ?, with respect to the normal and undergoes a total internal reflection at the core-cladding interface as shown in the following figure.
a)Find the critical angle ?c for the core-cladding boundary.
b)Calculate the angle of incidence ?1.
c)
If the angle of incidence ?1 = 65°, will the ray of light undergo total internal reflection at the core-cladding interface? Explain your answer.
When a ray of light enters a glass lens surrounded by air, it slows down. (a) As it leaves the glass, does itsspeed increase, decrease, or stay the same? (b) Choose the bestexplanation from among the following:I. Its speed increases because the ray is now propagating in amedium with a smaller index of refraction.II. The speed decreases because the speed of light decreaseswhenever light moves from one medium to another.III. The speed will stay the same because the speed of light is auniversal constant.
When a drop of water is placed on a flat, clear surface such as a glass slide or plastic sheet, surface tension pulls the top surface into a curved, lens-like shape so that the drop functions as a simple magnifier. Suppose a drop of water has a maximum angular magnification of 3.70. (Use 1.333 for the index of refraction for water.)
HINT
(a)
Find the drop's focal length in cm.

(b)
Assuming the bottom surface of the drop is flat, use the lens-maker's equation from Topic 23 to calculate the radius of curvature (in cm) of the top surface.
