A ray of light is incident on a prism of refracting angle A. if `theta_(C)` is the critical angle for the material of the prism with respect to the surrounding air, then:

Options

A. An emergent ray will be there for all values of `theta_(C)`
B. An emergent ray will be there only for `A le 2 theta_(C)`
C. A ray incident at an angle I can pass through the prism if `sin gt (sin(A-theta_(C)))/(sin theta_(C))` for `theta_(C) lt A lt 2 theta_(C)`
D. None of above is correct
