(a) A
(b) B
(c) C
(d) D

Q. Four students A, B, C and D showed the following traces of the path of a ray of light passing through a rectangular glass slab.



The trace most likely to be correct is that of student:
(1) A
(2) B
(3) C
(4) D

Q. In an experiment to trace the path of a ray of light passing through a rectangular glass slab, four students measured the angles of incidence (i), angles of refraction (r) and angles of emergence (e) as shown in the diagrams:



The correct measurement is given in the diagram:
(1) A
(2) B
(3) C
(4) D

Q. A student traces the path of a ray of light passing through a rectangular glass slab.



For measuring the angle of incidence, he must position the protractor in the manner shown in figure:
(1) A
(2) B
(3) C
(4) D
