Question

each caso. Number the beams and note that the prism inverts their order Part X: Deviation due to a Prism (H) Use the 60 angle as the angle of the prism. Trace the path of light through the prism for incident angles of approximately 35, 45, and 75. The angle of deviation is the angle formed by the forward extension of the incident beam and the backward extension of the emergent beam. How does the deviation vary with the angle of incidence? ls there a minimum angle of deviation? Rotate the prism and watch the emergent beam. Introduce a red filter. Adjust the prism for minimum deviation for red. Draw sufficient rays (as in the figure below) to find the minimum angle of deviation. Find the index of refraction, n, of the prism material, using the formula: sin (A +amin) sin A AIA 212 θα rt Part XI. Dispersiorn With the 60 prism set as in Part X for white light, observe the spectrum of white light. Carefully record the difference in the value for the angle of minimum devia tion for red and for violet. This difference is the angle of dispersion for the prism

This was the last part of my physics 204 class. We were not able to complete the lab because of time constraints. Do you know how I would approach this/what the drawing would look like/how to approach the questions? Thank you!
