    Can you get a critical angle for air towater interface? Or can you get total internal reflection in air when theincident ray hits water boundary from air?
    The equation: sinqc = n2/ n1 for n1> n2but... n1 = air = 1 n2 = water = 1.34so... n1 < n2 which can’t be calculated?
    Is the attached diagram possible?

    Not possible. For total internal reflection to occur, the reflective index of the external substance must be a higher number.

    As for the reflection of light from water surface, it is simple reflection, just like in mirror.
