Respuesta :
The refractive index of the liquid is 1.52. The substance is a crown glass.
Explanation:
Given:
Velocity of light through the substance, v = 1.97 X 10⁸ m/s
Refractive index of the liquid, μ = ?
We know,
μ = [tex]\frac{c}{v}[/tex]
where, c = velocity of light in air
v = velocity of light in the substance
speed of light in air is 3 X 10⁸m/s
[tex]= \frac{3 X 10^8}{1.97 X 10^8} \\\\= 1.52\\[/tex]
Therefore, refractive index of the liquid is 1.52. The substance is a crown glass.
n = 1.52
Index of the liquid = 1.52
The type of the liquid is Crown glass.
Explanation:
In finding the index of refraction, we use this formula
n = c/v
where n is the index of refraction
c is velocity of light in vacuum which is constant and is equivalent to [tex]3 \times 10^{8} \mathrm{m} / \mathrm{s}[/tex]
v is the velocity of light in a particular medium
Here we use [tex]1.97 \times 10^{8} \mathrm{m} / \mathrm{s}[/tex]
Using the formula,
n = c/v
n = [tex]3 \times 10^{8} / 1.97 \times 10^{8}[/tex]
n = 1.52284264
n = 1.52
Thus, the index of the liquid is 1.52
