At the boundary, part of the light is refracted and part B) Calculate the angle of refraction of the incident light ray. Al Using a protractor, measure the angle of incidence of the light ray at the air-fused quarts C) Using a protractor and straightedge, construct the refracted light ray in the fused quartz on D) Using a protractor and straightedge, construct the reflected ray on the diagram. Normal 5) "Challenge" A ray of monochromatic light (f - 5.09 x10" Hz) passes through air and a rectangular transparent block, as shown in the diagram below. A) Using a protractor, determine the angle of incidence of the light ray as it enters the Incident light ray transparent block from air B) Draw and label the reflected ray off the air and transparent block interface, C) Calculate the absolute index of refraction for the medium of the transparent block D) Calculate the speed of the light in the transparent block.
