A hemispherical transparent paperweight of radius 5m and refractive index 1.5 is placed on a table. A beam of lazar, at a distance of 2m from the centre is directed as shown in the figure.
1. Name the law which is related to refraction.
2. Locate the position of the image by completing the ray diagram.
3. With the source of laser at the centre of the hemisphere, redraw the ray diagram.
