Answer:
a) glycerin n = 1.5440 , quartz n = 1.4730
b) n₂₁ = 0.550
Step-by-step explanation:
The refractive index is
n = c / v
where c is the speed of light in a vacuum and v the speed of light in the material medium
Let's use this expression to find the indexes of refraction
a) glycerin of v= 194166099 m / s
n = 2,998 10 8/194166099
n = 1.5440
quartz v = 203525090 m / s
n = 2,998 108/203525090
n = 1.4730
b) the relative refractive index is the relationship between the absolute refractive indices of two materials
diamond n₁ = 2.417
water n₂ = 1.33
the relative refractive index
n₂₁ = n_water / n_diamond
n₂₁ = 1.33 / 2.417
n₂₁ = 0.550
