Question

What is the merit of the method described in the experiment of r.i of liquid by concave mirror

Answer 1

Answer:

Measuring the refractive index n of a substance or medium is part of various approaches that are used to determine this index. These approaches have been developed over the years based on the different ways light reflects and transmits in the medium.

One of those methods involves a spherical concave mirror filled with a liquid, which makes itself an excellent alternative to measure the refractive index of the liquid, especially when no advanced apparatuses are available, and the accuracy of the measurements is not critical.

In this experiment, we will be using the concave mirror method in order to determine the refractive index of water.

Answer 2

Advantages of finding Refractive index of a material by a spherical concave mirror

• In the experiment a spherical concave mirror filled with liquid is used to find the refractive index of liquid
• It is a simple and accurate method of describing refractive index of water
• The experiment is easy to setup and perform
• The experiment is well suitable for undergraduate physics laboratory
• One of the main advantage is the real image may be observed at the center of curvature of empty mirror when the object is placed at same point
