1. What is refractive index of a material? Which material has the highest refractive index?
Answers
Answer:
Germanium
Answer. The ratio of speed of light in vacuum to the speed of light in a medium is called the refractive index of that medium. Germanium has the highest refractive index of 4.05.
hope it helps

What is refractive index of a material?
Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. ... Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.
Which material has the highest refractive index?
A whopping 38.6
Explanation:
Researchers in Korea have created a new metamaterial with the most extreme positive index of refraction yet – a whopping 38.6. The metamaterial operates at terahertz frequencies and the team believes that it could find use in a number of applications including high-resolution imaging.
