What is the least count of a travelling microscope?

Answer: LC = 0.001 cm Travelling microscope is a compound microscope that is fitted on the vertical scale. It carries a vernier scale along the main scale and can be moved upward or downward. So the smallest division on the main scale of the travelling microscope is = 0.5 mm.

Why this microscope is called as travelling microscope?

Since this microscope can be taken outside of the laboratory for observations, therefore, it named travelling microscope.

What are the applications of travelling microscope?

Travelling microscope is used for accurate measurement of the diameters of different objects. It is also used in Physics Laboratories for more accurate determination of small variation in the liquid levels, Manometers, the refractive index of liquids as well as in surface tension & viscosity experiments.

What is the range of travelling microscope?

Short distances can be measured precisely using a microscope. Travelling microscope has an accuracy of 0.01mm. In a typical Travelling microscope, the main scale divisions are of magnitude 0.05cm and the vernier scale contains 50 divisions.

Which of the following is most precise instrument for measuring length?

Screw gauge has minimum least count of 0.001cm. Hence, it is most precise instrument.

How many scales are there in travelling microscope?

The vernier scale of a travelling microscope has 50 divisions which coincide with 49 main scale divisions.

Which lens is used in travelling microscope?

Concave mirror and Plano concave mirror are used in the microscope. In a typical Travelling microscope, the main scale divisions are of magnitude 0.05cm and the vernier scale contains 50 divisions. So with such a small scale, focal length can’t be measured either of a convex mirror or a convex lens.

Is travelling microscope a compound microscope?

Travelling microscope is an example of a Compound microscope. It provides a 2-D image. It is fitted on a vertical scale. It has a vernier scale along the main scale and can be moved upward or downward according to our requirements.

Which is a precision instrument?

precision instrument in British English (prɪˈsɪʒən ˈɪnstrəmənt) an instrument or tool which is used for tasks which are precise or exact in nature.

What is a travelling microscope used to measure?

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

What is a 657 traveling microscope?

Nvis 657 Traveling Microscope is an extensively used product in Research, Colleges, Schools and Industrial laboratories for accurate measurement of the diameters of different objects. Two slow motion knobs are provided for taking accurate readings. For placing objects on horizontal stage, milky cenolite sheet is provided on the base.

What is the size of the scale of microscope?

The scale is divided in half millimeters. Fine adjustments are made by means of a micrometer screw for taking accurate reading. Both vernier reading to 0.01mm or 0.02mm. Microscope tube consists of 10x Eyepice and 15mm or 50mm or 75mm objectives.

How do you adjust the position of a microscope?

The position of the microscope can be varied coarsely by sliding along the rails, or finely by turning a screw. The eyepiece is fitted with fine cross-hairs to fix a precise position, which is then read off the vernier scale.
