WebApr 4, 2024 · In this practical video of finding the refractive index, the reading is being taken by placing the travelling microscope perpendicular to the slab. But I've learned in another video() if you are watching directly from the above (incident angle is 0°) then the Real depth = Apparent depth.And I am sure that In the above situation the below refractive index … WebThus the microscope can be moved both in the vertical and horizontal directions. Two fine adjustment screws are provided for the horizontal and vertical movements respectively. …
Vernier Calipers Made Easy - Concepts of Physics
WebThe travelling microscope usually used has each mm divided equally into two halves. So the smallest division on main scale will be 0.5 mm. So the smallest division on main scale will be 0.5 mm. There are 50 divisions on the vernier scale.i.e it has vernier scale divisions so readings would be taken through it. A travelling microscope is an instrument for measuring length with a resolution typically in the order of 0.01mm. The precision is such that better-quality instruments have measuring scales made from Invar to avoid misreadings due to thermal effects. The instrument comprises a microscope mounted on two rails fixed to, or part of a very rigid bed. The position of the microscope can be varie… css li active

WebTravelling Microscope is extensively used in Research, Colleges, Schools and Industrial laboratories for accurate measurement of the diameters of different objects. Two slow … WebDec 15, 2010 · Study now. See answer (1) Copy. let us think with all our common sense. The indicator which reads the reading on the main scale is the zero mark on the vernier. On the main scale each mm is divided into half mm. Hence the reading would be read for divisions on the main scale. ie say I start from 3 cm. WebJan 12, 2024 · Place the glass slab of least thickness over the mark P. Raise the microscope upwards and focus it on the image P1 of the cross-mark. Note the reading (R2) on the vertical scale as before (Step 3). Sprinkle a few particles of lycopodium powder on the surface of the slab. Raise the microscope further upward and focus it on the particle near S. css library ui
