Measurement Of Refractive Index Of A Liquid By A Travelling Microscope

Thin lens (Part-3)|Finding the refractive index of a liquid using concave mirror| lens mirror combination

Assertion : The radius of curvature of a mirror is double of the focal length. Reason : A concave mirror of focal length f in air is used in a medium of refractive index 2. Then the focal length of mirror in medium becomes 2f.

A glass lens of refractive index 1.5 is placed in a trough of liquid. What must be the refractive index of the liquid in order to mark the lens disappear?
