Measurement Of Refractive Index Of A Liquid By A Travelling Microscope

Measurement Of Refractive Index Of Liquid By A Convex Lens

Measurement Of Refractive Index Of Liquid By A Concave Mirror

To determine refractive index of glass slab using a travelling microscope, minimum num- ber of readings required are :

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

While determining the refractive index of a liquid experimentally, the microscope was focussed at the bottom of a beaker, when its reading was 3.965 cm. on pouring liquid upto a height 2.537 cm inside the beaker, the reading of the refocussed microscope was 3.348 cm. Find the refractive index of the liquid.

A travelling microscope is focussed on to a scratch on the bottom of a beaker. Water of refractive index (4)/(3) is poured in it. Then the microscope is to be lifted through 2 cm focus it again. Find the depth of water in the beaker.

Light is incident normally on the short face of a 30^@-60^@-90^@ prism. A liquid is poured on the hypotenuse of the prism. If the refractive index of the prism is sqrt(3) , find the maximum refractive index of the liquid so that light is totally reflected.

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 make the lens disappear ?
