a ray of light is normally incident on one face of an equilateral glass prism . what will be the angle of incidence at the second face of the prism and how? plssss... draw a completed diagram for this question?
the angle of incidence at the second face will be 90 degree. as the incident angle is more than the critical angle of the medium and therefore total internal reflection will happen and the light will come out of the prism perpendicularly.
