Please refer to Figure 2. A light beam shines through air and then strikes a mirror, making an angle theta = 48.4 degrees with respect to the vertical, as shown. The reflected beam then strikes a pane of glass of thickness h = 1.97 cm, located a distance y= 40.0 cm from the mirror, and then exits the glass pane at the bottom, a horizontal distance x cm away from where it struck the mirror. What is the value of x?

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

A mirror hangs 1.60 m above the floor on a vertical wall. A ray of sunlight, reflected off the mirror, forms a spot on the floor 1.14 m from the wall. Later in the day, the spot has moved to a point 2.50 m from the wall. (a) What is the change in the angle of elevation of the Sun, between the two observations?                       °(b) What time of day were these observations made? morning or afternoon

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 layer of oil (n = 1.45) floats on an unknown liquid. A ray of light originates in the oil and passes into the unknown liquid. The angle of incidence is 60.9 degrees, and the angle of refraction is 69.2 degrees. What is the index of refraction of the unknown liquid?

A light ray in a vacuum is an incident on an equilateral triangular prism. It makes an angle of 13.2 degrees with the normal of the prism's surface. It makes an angle of 12.4 degrees with the normal after entering the prism. What is the angle it makes with the far side's normal after exiting the prism?

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 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

ray of light strikes a flat block of glass at an incidence angle of ?1 = 38.6°. The glass is 2.00 cm thick and has an index of refraction that equals ng = 1.52.   a.)What is the angle of refraction, ?2, that describes the light ray after it enters the glass from above? (Enter your answer in degrees to at least 2 decimal places.)   b.) With what angle of incidence, ?3, does the ray approach the interface at the bottom of the glass? (Enter your answer in degrees to at least 2 decimal places.)     c.) With what angle of refraction, ?4, does the ray emerge from the bottom of the glass? (Enter your answer in degrees to at least 1 decimal place.)     d.) The distance d separates the twice-bent ray from the path it would have taken without the glass in the way. What is this distance (in cm)?     e.) At what speed (in m/s) does the light travel within the glass?    f.) How many nanoseconds does the light take to pass through the glass along the angled path shown here?
