An experiment is performed to find the refractive index of glass using a travelling microscope. In this experiment distances are measured by (a) a vernier scale provided on the microscope (b) a standard laboratory scale (c) a meter scale provided on the microscope (d) a screw gauge provided on the microscope

Answer: (a). A travelling microscope reads the real and apparent positions of a mark on its vernier scale. μ = (real depth)/(apparent depth) is found from these vernier readings. So the answer is (a).

An experiment is performed to find the refractive index of glass using a travelling microscope. In this experiment distances are measured by

Show answer and solution

Answer: (a)

A travelling microscope reads the real and apparent positions of a mark on its vernier scale.
$\mu = \dfrac{\text{real depth}}{\text{apparent depth}}$ is found from these vernier readings.
So the answer is (a).
