A ray of light is passing from air into glass. If the angle of incidence, with respect to the normal to the interface, is increased: a. Total internal reflection will occur when the angle of incidence equals the critical angle
b. Total internal reflection will occur when the angle of incidence is less than the critical angle
c. Total internal reflection will occur when the angle of incidence is greater than the critical angle
d. Angle of refraction will increase but there will be no total internal reflection
