PHYS 1502Q Chapter Notes - Chapter 24, 25: Srf 1, Total Internal Reflection, Patent Lens
Document Summary
Assume light travels in straight lines (rays) Concerns with reflection and refraction of rays at the interface of two material. I = r (where both angles are measured with respect to the normal) 0 are constants magnetic constant permeability of free space vacuum permeability and electric constant permittivity of free space vacuum permittivity, respectively. D = 0 + 0 0. D = + d. 0 0 n = v c = sin . 1 sin 2 = n2 n1 sin 1 increases but. Angle between refracted ray and reflected ray is 09 . 2 = n1 sin sin sin n2 n1. Lenses - transparent materials that are constructed so that parallel rays are refracted towards a point (the focus) Converging lense - parallel rays are refracted into the glass towards the normal and then reflected back into the air away from the normal. Rays are converging and intersect at a real focus on the downstream side of the lens.
