What is the unit of refractive index .............
Answers
The refractive index unit says that is:
- There are no SI units of the refractive indicator, as it is a measure of the speed of light of relative importance.
- Light speed in vacuum, all speed units are cancelled and only the remaining number indicates the ratio.
- The refractive index unit (μ) will be the unit of light in vacuum (c) and light speed in a given area (v).
- As you can see, the refractive unit is 1, which means the refractive index is just a number without any unit.
- The vacuum has 1 refractive index.
Answer:
Refractive index is a unitless unit.
Explanation:
Snell's Law:
Snell's Law connects the refraction and incidence angles to the media's refraction indices. According to Snell's Law, the product of the sine of the angle created by the light ray, the regular straight line, and the media's refractive index must remain constant.
Refractive index:
A material's refractive index, which is quantified, indicates how much a light path is bent or refracted when it penetrates that material. The critical angle for total internal reflection and the amount of light that is reflected when it reaches contact are both determined by the index of refraction.
The formula of refractive index is
n = c / v
n is the index of refraction
c is the speed of light in a vacuum (or air)
v is the speed of light in the media (e.g. water, veg. oil, etc.)
The units of c and v are the same. Thus n has no unit.
