Answer:
1.3636
Explanation:
Write the expression for the refractive index.
n=c/v
c= speed of light in air
v= speed of light in material
=(3×10^8 m/s)/(2.2×10^8 m/s)
=1.3636
Answer:
The material is silica quartz.
Explanation:
Given that,
Speed of light in material [tex]v=2.07\times10^{8}\ m/s[/tex]
Speed of light in vacuum [tex]c=3.00\times10^{8}\ m/s[/tex]
We need to calculate the refractive index
Using formula of refractive index
[tex]n=\dfrac{c}{v}[/tex]
Where, c = Speed of light in vacuum
v=Speed of light in material
Put the value into the formula
[tex]n=\dfrac{3.00\times10^{8}}{2.07\times10^{8}}[/tex]
[tex]n=1.44[/tex]
We know that,
Refractive index of silica quartz is between 1.40 to 1.55
So, This is the refractive index of silica quartz.
Hence, The material is silica quartz.
