n=c/vrefraction equation where n=index of refraction, c=speed of light in a vacuum, v=speed of light in that materialSnell's lawdescribes how light behaves when passing from one material to another, light passes through an object, but is deflected off its original line, amount of refraction is based on the object's optical density and incident anglen1sinθ1=n2sinθ2Snell's law equation where is n is refractiontotal internal reflectionlight attempts to pass from one material to another, light must be traveling from a more dense to a less dense material, if the incident angle is larger than the critical angle (θc), then light is reflected, law of reflection applies (θi=θr)sinθc=n2/n1total internal reflection equationtypes of lensesplane: flat lens (window), always gives a real image convex: curved towards the object (symmetric on both sides), gives virtual or real image concave: curved away from object (symmetric on both sides), gives virtual or real images1/f=1/di+1/do (lense)lens equation where f=focal point, di=distance to image from lens, do=distance to object from lensM=hi/ho=-di/do (lense)magnification equation where M=magnification, hi=height of image, ho=height of object, di=distance from image to lens, do=distance from object to lenscomparing singles to doubles1 wavelengths difference in path length from the edges of the slit produces a minimum since the light from the center of the slit differs by a half wavelength and gives destructive interferencesingle slit diffractiondouble slit interferencey=mλD/dcomparing singles to doubles equation #1dsinθ=mλcomparing singles to doubles equation #2
