A) At Distance of 11 cm and Image is virtual if \[X=12\text{ }cm\]
B) At Distance of 11 cm and Image is virtual if \[X=14\text{ }cm\]
C) At the Distance of 11 cm and Image is Virtual if \[X=16\text{ }cm\]
D) All the above
Correct Answer: D
Solution :
[d]As rays are parallel to the principal axis, image is created by lens at the focus. |
By placing of glass-slab, \[\text{shift}\,\text{=}\left( 1-\frac{1}{\mu } \right).t\] \[\,\text{=}\left( 1-\frac{1}{1.5} \right)3=1\,\,cm.\] |
Irrespective of separation, Image is shifted to the right by 1 cm. |
Total distance from lens \[10+1=11\,cm\] |
Image will be virtual if X is greater than 11 cm |
