The indices of refraction for her contact lens, cornea, and the fluid behind her cornea are 1.6, 1.4, and 1.3, respectively. Light is incident from air onto her contact lens at an angle of 30 ∘∘ from the normal of the surface. At what angle is the light traveling in the fluid behind her cornea?

Explanation:

n = Refractive index of air = 1

= Refractive index of contact lens = 1.6

= Refractive index of cornea = 1.4

= Refractive index of fluid = 1.3

From Snell's law

The angle is the light traveling in the fluid behind her cornea is .

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
