These sketches show light rays as black arrows refracting when moving from one medium to another, where the solid blue line is the surface and the dotted line is the perpendicular or normal line. Some are drawri correctly and some are not. For each one, check the best answer. (Hint: remember that when n increases. light bends in toward the normal line.) 6) The ray in number 6 (Q is correct as drawn. 0 should bend to the left. O should bend to the right. 0 should go straight without bending. 7) The ray in number 7 Q is correct as draWn. Q Should bend to the left. should bend to the right. 0 should go straight without bending. 8) The ray in number 8 (9 is correct as drawn. O should bend to the left. 0 should bend to the right. 0 should go straight without bending. 9) The ray in number 9 O is correct as drawn. 0 should bend to the left. O should bend to the right. should go straight without bending. 10) In which of the numbered cases above would light reect completely Earn the surface if the angle of incidence grew larger and larger? That is, in which case could total internal reection occur? (Hintzin which of the four cases is the change in n not like the others?) 06 O7 08 9
