    Help with radius of curvature and refractive index of lens

    Im doing a unit were I have to do extra studies which are not really touched on in the lecture notes. So, I quite out of my ball park on this one, and I am completely lost of the two different n values.

    Optics question with radius of curvature

    Hi, I am a first time poster and I am completely lost with this question. Any help would be greatly appreciated Filling the space between a contact lens and the cornea is a small quantity of liquid of refractive index of 1.336. Assuming the refractive index of the lens material is 1.490 find...
