Explain how refracted angles change with increasing incident angles. What is different when incident angle is 60 degrees? Explain in detail with respect to reflection and refraction

2. In the image below, an incident ray shines at an angle onto two layers of class. The first layer has an index of refraction of 1.47. The second layer is of an unknown index. You have determined the point at which the ray exits the second layer of glass. You will need a protractor to measure angles in this problem. (A) Determine the angle of refraction of the ray inside the first material. (B) Trace the path of the ray through the first and second layers of materials on the picture below. (C) Determine the unknown index of refraction in the second material. (D) Determine direction of and draw the path of the ray after it exits the second layer. point where ray exits second layer. air n2 = ? ni = 1.47 air incident ray

"If medium 1 is air and medium 2 is acrylic, what will be the angle of incidence if the angle of refraction is 30 degrees ?" A) 54.73 deg B 30 deg c) 48.59 deg 19.47 deg
