A glass hemisphere of radius 0.04 m and R.I. of the material 1.6 is placed centrally over a cross mark on a paper (i) with the flat face ; (ii) with the curved face in contact with the paper. In each case the cross mark is viewed directly from above. The position of the images will be
- (i) 0.04 m from the flat face; (ii) 0.025 m from the flat face
- (i) At the same position of the cross mark ; (ii) 0.025 m below the flat face
- (i) 0.025 m from the flat face; (ii) 0.04 m from the flat face
- For both (i) and (ii) 0.025 m from the highest point of the hemisphere
Answer
(B) (i) At the same position of the cross mark ; (ii) 0.025 m below the flat face
