Calculate the percentage of light refracted and reflected using the refractive indecies and incident angle?

I know the angle of incidence.

I know the refractive indexes of the two mediums either side of the interface I am considering.

I can use Snell's law to calculate the angles of refraction and reflection.

But how can I calculate what percent of the light is reflected and what percent refracted?



Thanks for any help...Calculate the percentage of light refracted and reflected using the refractive indecies and incident angle?
To solve this problem, you need to find the transmission and reflection coefficlents, which can be found using the given angle of incidence, the angle of refraction you have found via Snell's Law, and of course the two indices of refraction.



You need to use the Fresnel equations to flind the coefficients of transmission and reflection:
