6) For a prism made of a small, triangular wedge of glass where the triangle is an equilateral triangle, what is the length of the spectrum formed if a point-like beam of white light strikes the input face of the prism making angle 50° with the normal, if the spectrum is visible on a screen 10 m from the prism itself. Assume the visible range is from 390 nm to 780 nm, with n(390nm) 1.50 and n(780nm) 1.45, and that the screen is normal to the output beam.
