23M.1A.SL.TZ1.16

A group of students perform an experiment to find the refractive index of a glass block. They measure various values of the angle of incidence i and angle of refraction r for a ray entering the glass from air. They plot a graph of the sin r against sin i.

They determine the gradient of the graph to be m.

Which of the following gives the critical angle of the glass?


A.  sin−1(m)

B.  sin−11m

C.  m

D.  1m
