5. A ray of blue light strikes a 60 triangular glass prism of refractive index 1.54 as shown. (a) Calculate the angle of refraction of the ray of blue light as it enters the glass prism. (b) If the speed of the blue light in air is 3.00 108 m/s, what is the speed of the blue light in the glass prism? (c) Calculate the angle of refraction of this ray of blue light as it emerges from the glass prism. (d) Briefly explain what you would expect to observe if the ray of blue light was replaced by a ray of white light? Ans: (a) 24-7 (b) 1.95 x 108 m/s (c) 62.9 Air 50 Glass prism
