Unformatted text preview: Formula Sheet - Physics 317L - Exam Lenses and Mirrors: reflection angle: Θ 1 = Θ 2 refraction angles: n 1 sin Θ 1 = n 2 sin Θ 2 , n = index of refraction total internal reflection: critical angel: Θ c = sin- 1 ( n 2 n 1 ) plane mirror: distance : i = -p spherical mirror focal length : f = 1 2 r , (r= radius) spherical mirror : 1 f = 1 p + 1 i magnification: | m | = h h magnification: | m | = - i p refraction on curved surface: n 1 p + n 2 i = n 2- n 1 r thin lenses: 1 f = 1 p + 1 i thin lenses in air: 1 f = ( n- 1)( 1 r 1- 1 r 2 ) adding 2 lenses: 1 f 1+2 = 1 f 1 + 1 f 2 magnification of 2 lenses: M = m 1 m 2 angular magnification: m Θ = Θ Θ simple magnification for Eyepiece lens: m Θ ∼ 25 cm f magnification of Objective lens: m = - s f ob , s = microscope length Interference and Diffraction: wavelength in medium : λ n = λ n interference at two slits : d sin Θ = mλ ; m = 0 , 1 , 2 , ... (maxima - bright fringe) interference at two slits : d sin Θ = ( m + 1 2 ) λ ; m = 0 , 1 , 2 , ... (minima - dark fringe) thin-film interference: 2 L = ( m + 1 2...
