Question

A beam of light propagating in medium $A$ with index of refraction $n\,\,\left( A \right)$ passes across an interface into medium $B$ with index of refraction $n\,\,\left( B \right)$. The angle of incidence is greater than the angle of refraction; $v\,\,\left( A \right)$ and $v\,\,\left( B \right)$ denote the speed of light in $A$ and $B$. Then which of the following is true

Accepted Answer

$v\,\,\left( A \right)\,\, > \,\,v\,\,\left( B \right)$ and $n\,\,\left( A \right)\,\, < \,\,n\,\,\left( B \right)$

Answer

$v\,\,\left( A \right)\,\, > v\,\,\left( B \right)$ and $n\,\,\left( A \right)\,\, > n\,\,\left( B \right)$

Answer

$v\,\,\left( A \right)\,\, < \,\,v\,\,\left( B \right)$ and $n\,\,\left( A \right)\,\,\, > \,\,\,n\,\,\left( B \right)$

Answer

$v\,\,\left( A \right)\,\,\, < \,\,\,v\,\,\left( B \right)$ and $n\,\,\left( A \right)\,\,\, < \,\,\,n\,\,\left( B \right)$
