Reflection Of light and Refraction at plane surface

Figure shows a transparent hemisphere of radius 3'0 cm made of a material of refractive index 2.0. (a) A narrow beam of parallel rays is incident on the hemisphere as shown in the figure. Are the rays totally reflected at the plane surface ? (b) Find the image formed by the refraction at the first surface. (c) Find the image formed by the reflection or by the refraction at the plane surface. (d) Trace qualitatively the final rays as they come out of the hemisphere.

Which of the following statement is // are correct about the refraction of light from a plane surface when light rays is incident in denser medium. [ C is critical angle ]

Unpolarised light is incident from air on a plane surface of a meterial of refractive index 'mu' . At a particular angle of incidence 'I' , it is found that the reflected and refracted rays are perpendicular to each other. Which of the following options is correct for this situation?
