two slabs with refractive indices 4/3 and 3/2 with thickness of 12cm and 8cm.calculate the effective refractive index....
plzz reply soon...
We know that the apparent shift in the position of object due to a glass slab of refractive index and thickness d is given by
Now according to question,
net shift due to given two slab is
Let there is a slab of net thickness d1+d2 = d and equivalent refractive index , then lateral shift is
so
Now putting the value of
