A ray of light strikes a plane water-air interface from within the water at an angle of incidence i. Which one of the following statements is correct?
A. If / is 90°, the angle of refraction will be the critical angle.
B. If / is less than the critical angle, all the light is retracted and the angle of refraction is greater than 1.
C. If / is less than the critical angle, some light is reflected and the angle of reflection is less than the critical angle.
D. If / is equal to the critical angle, the reflected and refracted rays will be at right angles to each other.
E. If / is less than the critical angle, all the light is refracted and the angle of refraction is less than i.
