Concept explainers
To show:The ray configuration cannot be achievedfor the given refractive index.
Answer to Problem 99A
The ray configuration is not achievable when
Explanation of Solution
Given:
The index of refraction is
The given figure is shown below.
Formula used:
The expression for Snell’s law of refraction is,
Here,
Consider the given Figure.The ray from the light enters the glass at an angle of
Hence, the index of refraction of the first medium
The angle of refraction by using Snell’s law of refraction is,
The angle
The critical angle of glass is,
The angle
Conclusion:
Thus, it is proved that the ray configuration is not achievable when
