A laser beam strikes one end of a slab of material, as in the figure below. The index of refraction of the slab is 1.52. Determine the number of internal reflections of the beam before it emerges from the opposite end of the slab. (Enter an integer for the total number of complete reflections. Assume = 43.4°.) complete internal reflections Ꮎ 42.0 cm T 3.10 mm

What is the critical angle for total internal reflection for glass in air? Assume that nglass= 1.50 and nair = 1.00.

A light ray in the core (n=1.40) of a cylindrical optical fiber is incident on the cladding. A ray is transmitted through the cladding (n= 1.20) and into the air. The emerging ray makes an angle 02 = 6.10° with the outside surface of the cladding. What angle 01 did the ray in the core make with the axis? Air

A prism made of flint glass has a cross section that is an equilateral triangle. The index of refraction for red and violet light respectively in flint glass is 1.662 and 1.698. If as shown in the figure, the angle of incidence in air for both colors of light is 66.8°, determine the angle at which both colors emerge back into air after traveling through the prism. red light                         ° violet light                          °

An object is placed 9.50 cm in front of the cornea. (The cornea is thin ans has approximately parallel sides so that the reflection that occurs as light travels from air to cornea to aqueous humor is essentially the same as though the aqueous humor were directly in contact with the air. The aqueous humor has index of refraction n = 1.34 and the radius of curvature of cornea is 7.8 mm.) (a) What is the image distance for the image formed by the cornea alone? (b) The image formed by the cornea serves as an object for the lens. Treat the lens as a thin lens 4 mm behind the cornea. Find the optical power of the lens necessary to form an image on the retina, 23 mm from the center of the lens.

The critical angle for total internal reflection within a fiber optic cable is θC = 24.1°. What is the index of refraction (n) for the material it's made from?

Two plane mirrors make the angle a = 58.0° between them. A ray of light incident on one of the mirrors is reflected and it hits the second mirror, as shown in the figure. Determine the angle ẞ between the ray incident on the first mirror and the ray reflected off of the second mirror. B = B

The index of refraction of a certain glass is (1.44x10^0). What is the critical angle for total internal reflection at the glass-air interface? Express your result in degrees with three significant figures.

As shown in the figure, a light beam travels from air, through olive oil, and then into water. If the angle of refraction 02 for the light in the olive oil is 28.2°, determine the angle of incidence 0, in air and the angle of refraction 03 in water. The index of refraction for olive oil is 1.47. 01 = 03 = air n2 oil 13 water
