A) 0.83
B) 0.94
C) 0.64
D) 0.15
Correct Answer: A
Solution :
The thickness of glass slab is \[t=2.5\text{ }cm\] and its the refractive index is \[\mu =15\] Now, shift due to glass slab \[D=\left( 1-\frac{1}{\mu } \right)t=\left( 1-\frac{1}{15} \right)2.5\] \[=\frac{1}{3}\times \frac{25}{10}=\frac{25}{30}=\frac{5}{6}\] \[=0.83\,cm\] Thus, microscope should be shifted 0.83 cm to focus the object again.You need to login to perform this action.
