The figure shows a transparent hemisphere of radius

3.0 \text{ 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.
$The figure shows a transparent hemisphere of radius 3.0 cm made of a material of refractive index 2.0 . (a) A narrow$

Options

A(a) They are reflected
(b) If the sphere is completed, the image forms at the point diametrically opposite to $A$
(c) At the mirror image of $A$ in $BC$
B(a) They are refracted
(b) If the sphere is completed, the image forms at the point diametrically opposite to $A$
(c) At the mirror image of $A$ in $BC$
C(a) They are reflected
(b) At the center of the hemisphere
(c) At the mirror image of $A$ in $BC$
D(a) They are reflected
(b) If the sphere is completed, the image forms at the point diametrically opposite to $A$
(c) At the pole of the curved surface

Correct answer

A. (a) They are reflected
(b) If the sphere is completed, the image forms at the point diametrically opposite to $A$
(c) At the mirror image of $A$ in $BC$

Step-by-step solution
