The direction of the ray of light enters equilateral 60° glass prism normal to the surface as shown in attached image
refracted index of the prism material for the violet light is 1.651
(a) What is the angle of incidence on the surface A-B?
(b) Does total internal reflection occur?
(c) Draw a ray diagram to show how light passes through
critical angle-----sin i c= 1/n
The Attempt at a Solution
a) critical angle
Not sure if its 90° for the incidence for side A-B
b) Total internal reflections occur because the angle of incidence is greater
then the critical angle
c) i also attached my attempt to the image.
thank you any help would be great
