The unknown material is glass because the refractive index is found out to be 1.5
Calculation and step-by step process
[tex]u_{water\\}[/tex]= 1.33
[tex]u_{x}[/tex]=?
[tex]u_{1}[/tex]sini=[tex]u_{2}[/tex]sin27°
[tex]u_{2}[/tex] = 1.33 x [tex]\frac{sin31}{sin27}[/tex]
= 1.33 x (0.51/0.45)
= 1.50
so, deducing from it, we have refractive index = 1.50
Hence the unknown material is glass.
What is index of refraction?
The refractive index (or refraction index) of an optical media in optics is a dimensionless quantity that indicates the capacity of that medium to bend light. The refractive index controls how much light is refracted or twisted when it enters a substance.
The angle of incidence and angle of refraction of a ray as it crosses the interface between two media with refractive indices of n1 and n2 are, respectively, n1 sin 1 and n2 sin 2, which describes this.
