Green light of wavelength 5400 A.U. enters the glass of R.I. 1.5, find the wavelength and frequency of light in glass.

As shown below, light from a vacuum is incident on a shard of Shawtonium (a newly discovered compound). The backside of the shard is up against an unknown material. When the light strikes the backside of the shard, total internal reflection occurs. The light then emerges from the side of the shard and resumes traveling through a vacuum. The index of refraction of Shawtonium is 2.5. Determine 01 & 02 unknown 0₂ shard vacuum 79° 30° 0₁ 0₁ = 0₂=

A flat sheet of ice (n = 1.309) has a thickness of 2.1 cm. It is on top of a flat sheet of crystalline quartz (n = 1.544) that has a thickness of 1.2 cm. Light strikes the ice perpendicularly and travels through it and then through the quartz. In the time it takes the light to travel through the two sheets, how far (in cm) would it have traveled in a vacuum? Number i Units

You are in a room lit only by blue light. A chair in that room looks black to you. (Your eyes see red + green light as yellow; your eyes see red+ blue light as magenta; your eyes see green and blue light as cyan)    a. What colors of light is the chair reflecting in the blue room? What colors of light is the chair absorbing in that room? Explain.   b. You then move the chair out into the sunlight. What possible colors could the chair be in the sunlight? Explain.
