A triangular prism is made using silica int glass with an index of refraction of 1.62 for red light and 1.66 for violet Below is a visual model for the dispersion of visible white light with an angle of incidence of 50.0 with respect to the left surface of the prism The prism is designed with an apex angle of sI> : 60.0", and the white light refracts such that the resulting outing beam disperses into a band of light in the form of a spectrum (note that the gure only shows the path of red and violet light for simplicity). initial beam of visible light spectrum of visible light a. Consider the behavior of the light at the left surface for the refraction of the red part of the original beam. Below is an incomplete figure of the geometry. Complete it by including the angle of incidence for the original beam and the angle of refraction of the red light. If any calculations are necessary, make sure to explain them. initial beam of visible light n airb. Next consider the red light as it is incident on the right surface of the prism. Make a sketch like the one above that includes the normal, angle of incidence, and angle of refraction of the outgoing red light. Explain any calculations and/or the application of any geometry to find the unknown angles. c. Repeat parts a and b for the violet light beam. - - - - initial beam of visible light - - - -- n aird. Calculate the angular deviation of the red light exiting the prism and the angular spread of the resulting color spectrum. Both are defined visually in the figure below. angular deviation of red light initial beam of visible light angular spread of spectrum n spectrum of visible light air
