Easy ! 1. effect observed when light from an object in cool air passes through warm air 2. line perpendicular to a surface 3. splitting of light into its component colors 4. alignment of light into a single vibrational direction 5. larger angle as light passes from air to water 6. cause of the sky's color 7. bouncing of light rays 8. bending of light between media 9. ratio of speeds of light 10. inability of light to escape a low-velocity medium due to a large angle of approach total internal reflection index of refraction mirage angle of incidence refraction dispersion reflection scattering normal polarization
