Vocabulary Word Definition(s) Notes on the Definition /Symbol/Scalar or Vector/ Units/Exam Image 17. Concave Lens 18 Real image A. Image formed by light rays that converge at the location of the image. A real image can be viewed or projected on a screen. 19. Virtual image A. Image formed by light rays that do not converge at the location of the image. Virtual images cannot be projected or displayed on a screenVocabulary Word Definition(s) Notes on the Definition /Symbol/Scalar or Vector/ Units/Exam Image 11. Optical axis A. For a mirror, a line perpendicular to the surface of a mirror that joins its focal point and center of curvature. B. For a lens, a line connecting the centers of curvature of the surfaces of the lens. 12. Focal point A. Point at which light rays that are parallel to the optical axis of an optical device either meet (converge) or diverge after being reflected or refracted. 13. Focal length A. Distance from the center of an optical device to the focal point.Vocabulary Word Definition(s) Notes on the Definition /Symbol/Scalar or Vector/ Units/Examples Image 14. Magnification A. Change in the apparent size of an object by an optical device or system 15. Refraction A. A process by The bending of light when it moves from which waves (including light) are medium to another. change direction by traveling into or through a surface or boundary between two materials. B. The angle between a refracted light ray and the normal to the surface at the point of contact is called angle of refraction. 16. Convex LensVocabulary Word Definition(s) Image Notes on the Definition /Symbol/Scalar or Vector/ Units/Examples 20. Snell's law of refraction A. Ratio of the sine of the angle of incidence to the in Q hisin D, = 12 Sin D2 sine of the angle of Sin Q2 - V2 hz refraction is a constant. The value of the constant is the ratio of the indices of refraction for the two materials. 21. Index of refraction A. Ratio of the speed of light in a vacuum to its speed in a material. B. A measure of how much a light ray bends when it passes from a vacuum into the material. 22. Total internal reflection A . Complete reflection of an incident light - Critical angle - angle of incidence at ray back into the which light is totally reflected back incident media. This occurs at a boundary into a material. with a material that has a lower index of refraction. Total internal reflection occurs at angles of incidence greater than a critical angle that depends on the difference in refractive indices.Vocabulary Word Definition(s) Notes on the Definition /Symbol/Scalar or Vector/ Units/Examples Image 8. Image A. Picture of an object that is formed by optical devices Object distance through reflection Image distance and/or refraction. 9. Convex Mirror 10. Concave MirrorVocabulary Word Definition(s) Notes on the Definition /Symbol/Scalar or Vector/ Units/Examp Image 6. Reflected ray A. A light ray that bounces off a surface or boundary between two materials. B. The angle between a reflected light ray and the normal to the surface at the point of contact is called angle of reflection 7.

Reflection Process by which waves (including light) bounce off or return by striking a surface or the boundary between two different materials. Specular reflection Reflection of light off smooth or shiny surfaces that produces a visible image of the object. c. Diffuse reflection - Light that strikes a surface that is rough (or not shiny) will scatter in many directions. a. A diagram showing how 4. Ray diagram the direction of light rays changes as they are reflected and/or refracted by optical devices. 5. Incident ray A. A light ray from an object that strikes a surface or boundary between two materials. The angle between a light ray that strikes a surface and the normal to the surface at the point of contact is called angle of incidence
