Travelling Microscope Practical

Theory & Formula

Measurement of capillary and rubber tube diameters using Vernier scale adjustment:

Least Count (L.C.) = 1 Main Scale Division - 1 Vernier Scale Division = 0.001 cm

Specimen Selection

Crosshair Positioned

Horizontal Movement (X-Axis)

MSR: 5.00 cm | VSR: 0

Vertical Movement (Y-Axis)

MSR: 5.00 cm | VSR: 0
