In finding out refractive index of glass slab the following observations were made through travelling microscope 50 vernier scale division = 49 MSD; 20 divisions on main scale in each cm For mark on paper
MSR = 8.45 cm , VC = 26
For mark on paper seen through slab
MSR = 7.12 cm , VC = 41
For powder particle on the top surface of the glass slab
MSR = 4.05 cm , VC = 1
(MSR= Main Scale Reading, VC = Vernier Coincidence)
Refractive index of the glass slab is:
For mark on paper seen through slab
For powder particle on the top surface of the glass slab
(MSR
Refractive index of the glass slab is:
