(b)
Answer to Problem 96PQ
The angle of incidence of the light ray at the sapphire air interface is
Explanation of Solution
Consider the diagram.
Figure-(1)
The above figure defines the light ray incident on the rectangular sapphire crystal at an angle of incidence is
Inside the sapphire crystal the ray travels in a straight line because the medium is same. So the angle of refraction at the air sapphire interface

- Unreasonable results Light traveling from water to a gemstone strikes the surface at an angle of 80.00 and has an angle of refraction of 15.2°. (a) What is the speed of light in the gemstone? (b) What is unreasonable about this result? (c) Which assumptions are unreasonable or inconsistent?arrow_forwardA beam of monochromatic light within a fiber optic cable is incident on one of the sides of the cable (n = 1.485) at an angle of incidence i. Assume the fiber is surrounded by air (n = 1.00029). a. What is the critical angle for total internal reflection so that the beam stays within the fiber? b. What would the critical angle be if the fiber were completely immersed in water (n = 1.33)?arrow_forwardA light ray is incident on an interface between water (n = 1.333) and air (n = 1.0002926) from within the air. If the angle of incidence in the air is 30.0, what is the angle of the refracted ray in the water?arrow_forward
- A narrow beam of light containing red (660 nm) and blue (470 nm) wavelengths travels from air through a 1.00-cm-thick flat piece of crown glass and back to air again. The beam strikes at a 30.0incident angle. (a) At what angles do the two colors emerge? (b) By what distance are the red and blue separated when they emerge?arrow_forwardUnreasonable results Suppose light travels from water to another substance, with an angle of incidence of 10.0and an angle of refraction of 14.9 . (a) What is the index of refraction of the other substance? (b) What is unreasonable about this result? (c) Which assumptions are unreasonable or inconsistent?arrow_forwardFigure P35.20 (page 958) shows a curved surface separating a material with index of refraction n1 from a material with index n2. The surface forms an image I of object O. The ray shown in red passes through the surface along a radial line. Its angles of incidence and refraction are both zero, so its direction does not change at the surface. For the ray shown in blue, the direction changes according to Snells law, n1 sin 1 = n2 sin 2. For paraxial rays, we assume 1, and 2 are small, so we may write n1 tan 1 = n2 tan 2. The magnification is defined as M = h/h. Prove that the magnification is given by M = n1q/n2p.

- The Sun appears at an angle of 53.0 above the horizontal as viewed by a dolphin swimming underwater. What angle does the sunlight striking the water actually make with the horizon?arrow_forwardA light ray travels from vacuum into a slab of material with index of refraction n1 at incident angle θ with respect to the surface. It subsequently passes into a second slab of material with index of refraction n2 before passing back into vacuum again. The surfaces of the different materials are all parallel to one another. As the light exits the second slab, what can be said of the final angle ϕ that the outgoing light makes with the normal? (a) ϕ > θ (b) ϕ < θ (c) ϕ = θ (d) The angle depends on the magnitudes of n1 and n2. (e) The angle depends on the wavelength of the light.arrow_forward
