1.	A spot is placed on the bottom of a slab made of transperent material of refractive index 1.5. The spot is viewed vertically from the top when it seems to be raised by 2 cm. Then, the height of the slab isA. 10 cmB. 8 cmC. 6 cmD. 4 cm
Answer» Correct Answer - C (c ) We have, `d_(app)=d/µ` or `(d-2)=d/1.5` `therefore` d=6 cm
