A ray of light travelling in air is incident at grazing angle (incidence angle `= 90^(@)`) on a medium whose refractive index depends on the depth of the medium. The trajectory of the light in the medium is a parabola, `y=2x^(2)`. Find, at a depth of 1 m in the medium
(i) the refractive index of the medium and
(ii) angle of incidence `phi`.
