Concept explainers
we must find the index of refraction of given material and identify the material.
Answer to Problem 76GP
Solution:
Refractive index of given medium is 1∙578 and the material is flint-glass.
Explanation of Solution
Given in the question that a pulse of light is traveling in certain medium and takes 2∙63 ns to travel 0∙500 m in that medium.
Given:
Given that Distance travelled = 0∙500 m
Time taken to travel the distance = 2∙63 n s=
Formula used:
Calculation:
Now refractive index of the medium = velocity of light in vacuum/velocity of light in medium
So refractive index of medium = =
So now we can check from the refractive index table that the material is Flint-glass.
