    A bubble in glass slab \[(\mu =1.5)\] when viewed from one side appears at 5 cm and 2cm from other side, then thickness of slab is:-

    A)  \[3.75\text{ }cm\]                  

    B)  \[3\text{ }cm\]

    C)  \[10.5\text{ }cm\]         

    D)  \[2.5\text{ }cm\]

    Correct Answer: C

    Solution :

    From one side, \[\frac{t-x}{5}=1.5\] From other side, \[\frac{x}{2}=1.5\] \[\Rightarrow \]\[7.5+3=10.5\,cm\] \[\therefore \]\[\frac{t-3}{5}=1.5\] \[\Rightarrow \] \[t=7.5+3=10.5\,cm\]
