Solution

The correct option is E The index of refraction of substance P is less than the index of refraction of substance G.
The angle the light ray makes with the normal is greater in material P.
Snell's law tells that $μ_{g} s i n i_{g} = μ_{p} s i n i_{p}$
Since $i_{g} < i_{p}$
$μ_{g} > μ_{p}$
Hence light has greater speed in material P.
