The figure is shown TO SCALE. Each block represents a 1.00 cm square. It shows a ray of light entering a rectangular piece of glass (n₂ = 1.50) from air (n₁ = 1.00). Find the position (x,y in cm) where the ray exits the glass. Or, if it does not exit the glass, find the (x,y) position of the second point (the second reflection) where total internal reflection occurs. In either case, be sure to check if total internal reflection occurs.

A ray of light crosses the boundary between some substance with n = 1.54 and air, going from the substance into air. If the angle of incidence is 29◦ what is the angle of refraction?   Calculate to 1decimal.

The drawing shows a rectangular block of glass (n = 1.52) surrounded by a liquid with n = 1.75. A ray of light is incident on the glass at point A with a 30.0° angle of incidence. At what angle does the ray leave the glass at point B? Number i Units 4

Using filters, a physicist has created a beam of light consisting of three wavelengths: 400 nm (violet), 500 nm (green), and 650 nm (red). She aims the beam so that it passes through air and then enters a block of crown glass. The beam enters the glass at an incidence angle of  ?1 = 31.5°. The glass block has the following indices of refraction for the respective wavelengths in the light beam. wavelength (nm) 400 500 650 index of refraction n400 nm = 1.53 n500 nm = 1.52 n650 nm = 1.51 (a) Upon entering the glass, are all three wavelengths refracted equally, or is one bent more than the others?   (b) What are the respective angles of refraction (in degrees) for the three wavelengths? (Enter each value to at least two decimal places.) (i) ?400 nm   (ii) ?500 nm   (iii) ?650 nm

The drawing shows a ray of light traveling from point A to point B, a distance of 7.80 m in a material than has an index of refraction n1. At point B, the light encounters a different substance whose index of refraction is n2 = 1.63. The light strikes the interface at the critical angle of Thetac = 49.2°. How much time does it take for the light to travel from A to B?

A beam of light traveling in air strikes a slab of transparent material. The incident beam makes an angle of 60° with the normal, and the refracted beam make an angle of 50° with the normal. What is the speed of light in the transparent material? (c = 3.0 × 108 m/s) Provide the answer: x 108 m/s

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

In the figure, light is incident at angle 8₁ = 39° on a boundary between two transparent materials. Some of the light travels down through the next three layers of transparent materials, while some of it reflects upward and then escapes into the air. If n₁ = 1.28, n₂ = 1.38, n3 = 1.34 and n4 = 1.45, what is the value of (a) 05 and (b) 04? 18₁ Air m n₂ 173 na

The drawing shows a ray of light traveling from point A to point B, a distance of 6.60 m in a material than has an index of refraction n₁. At point B, the light encounters a different substance whose index of refraction is n₂ = 1.63. The light strikes the interface at the critical angle of 8= 48.1°. How much time does it take for the light to travel from A to B? Number i Units *₂= 1.63 #1
