Geometrical and Physical Optics: 87 The wave behavior of light is proven by diffraction, interference and the polarization of light. Geometrical and Physical Optics: 88 The particle behavior of light is proven by the photoelectric effect. Geometrical and Physical Optics: 89 The electromagnetic spectrum (radio, microwaves, infrared, visible, ultraviolet, x-ray and gamma rays) is listed from lowest frequency to highest (longer to smaller wavelength). Geometrical and Physical Optics: 90 The range of wavelengths for visible light goes from 400 nm for violet to 700 bm for red. Geometrical and Physical Optics: 91 All angles in reflection and refraction are measured with respect to the normal. Geometrical and Physical Optics: 92 At the critical angle a wave will be refracted to 90 degress. Geometrical and Physical Optics: 93 Total internal reflection occurs at angles greater than the critical angle. Geometrical and Physical Optics: 94 Light rays bend away from the normal as they enter a lower index of refraction medium while the frequency remains constant. Geometrical and Physical Optics: 95 Light bends toward the normal and has a shorter wavelength when it enters a higher index of refraction medium while the frequency remains constant. Geometrical and Physical Optics: 96 In Young's double-slit experiment interference and diffraction account for the production of bright and dark fringes. Geometrical and Physical Optics: 97 Single slit diffraction produces a mcuh wider central maximum than double slit. Geometrical and Physical Optics: 98 Waves in phase undergo constructive interference; waves out of phase (1/2λ) will undergo destructive interference. Geometrical and Physical Optics: 99 When light reflects from a medium with higher index of refraction than that of the medium in which it is traveling, a 180o phase change (1/2λ) occurs. Geometrical and Physical Optics: 100 For a single optical device, real images are always inverted and virtual images are always upright.
