can u please tell me the least count of traveling microscope…???
The travelling microscope usually used has each mm divided equally into two halves.
So the smallest division on main scale will be 0.5 mm.
There are 50 divisions on the vernier scale.
Hence, the least count of travelling microscope is
L.C. = smallest division on main scale/number of divisions on the vernier scale
L.C. = 0.5/50 = 0.01 mm = 0.001 cm.
