What is the index of refraction of a material for which the wavelength of light is 0.671 times its value in a vacuum

Explanation:

We need to find the index of refraction of a material for which the wavelength of light is 0.671 times its value in a vacuum.

The wavelength in any medium is given by :

Where, is wavelength in vacuum and n is refractive index of the medium.

So, the medium can be PMMA (acrylic, plexiglas, lucite, perspex) which have a refractive index of 1.49.

it breaks and dirupture other materials and other sencews from the bottom

f=ma newton

f=100x2.5=250n
