Document Summary

Refraction at a spherical surface: p = ((n - n ) / r) = (n / p) + (n / q) Thin lens system image 1 image in separate document. P + p = (n / p) + (n / q) Lens creates an image in the same way as seen so far. P = [(nl - n ) / r ] + [(n - nl) / r ) P = (nl - n)((1/r ) - (1/r ) = (n / p) + (n / q) Thin lens in a continuous medium n = n = n. An object at inpinity: beams are coming in parallel rays onto lens. In general: (1 / f ) = (1 / p) + (1 / q) When n = n = n m = - (p / q) Ability of the human eye to focus on both close objects and distant objects.
