QUIZ:                             

Refractive Index                 

    

Study the two images above. Then choose the description below that most accurately describes the mineral immersed in the oils.

The refractive index of the mineral is equal to that of OIL 1 
The refractive index of the mineral is equal to that of OIL 2 
The refractive index of the mineral is closest to that of OIL 1 
The refractive index of the mineral is between that of OIL 1 and OIL 2 

When the refractive index of a mineral is equal to the refractive index of the immersion oil this means that: 

The clarity and color of both materials are the same 
The speed of light is the same within both materials 
The viscosity of both materials are the same 
Light is absorbed to the same degree in both materials
