A lens uses the process of refraction to deflect light rays from passing through it.
Answer:
Refractive index, n = 2.419
Explanation:
It is given that,
Speed of light in the medium, 
Speed of light in the vacuum, 
Let n is the index of refraction for a medium. We know that the refractive index for any medium is equal to the ratio of speed of light in vacuum to the speed of light in medium. It can be written as :


n = 2.419
So, the index of refraction for a medium is 2.419. Hence, this is the required solution.
Answer:
i wanna say tranverse if not surface
Explanation:
F=mass times acceleration so multiple 50 by 1.5 and u get 75
High school???
No way
It's work.
