- A beam of light traveling through air is incident up a transparent material with refractive index 1.52 at an angle of 0;=28.34 as shown in the image below. What is the angle of the transmitted ray (0t) as measured with respect to the direction normal to the surface of the material (dashed line in the image below). Normal Reflected Incident ray ray Transmitted ray Note: It is understood that the unit of your answer is in degrees, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.As shown in the figure below, light is incident at an angle 01 from a material with n1 = 1.2 to a material with n2 = 1.6. n3 n2 What is the smallest value of 01 so that there is total internal reflection at the interface between n2 and n3? (Assume n3 = 1.0) Express your answer in degrees, to at least one digit after the decimal point.Analyze the diagram below. Each segment of the umbrella appears to be a different color. Explain why each section appears to be the color that you see. Answer using 3 to 5 complete sentences.
