SNC2P Optics Test Review Name: _________________________ Match the appropriate word from the word list with the correct description in column A. Angle of incidence Convex mirror Normal focal length Non-luminous Principal axis Angle of Reflection Incident Ray Plane mirror Incandescence Chemiluminescence Bioluminescence Specular reflection Diffuse reflection Translucent Transparent Opaque Luminous Red Magenta Column A Answer Write the correct word below A line that is perpendicular to the surface normal A smooth, flat reflecting surface plane mirror A light source from a chemical reaction chemiluminescence The angle between the reflected ray and the normal angle of reflection The distance from the mirror to the focal point focal length A light ray that travels towards the mirror incident ray A line drawn normal to the centre of a spherical mirror principal axis A type of mirror that always produces a virtual image that is smaller than the object convex mirror (diverging) A source that produces its own light luminous Light emitted from a material being heated incandescence A light source found in living organisms bioluminescence An example of a primary additive colour Red (red green Blue) The type of reflection off an irregular surface Diffuse A material that scatters light Translucent The angle between the incident ray and the normal angle of incidence A object that only reflects light non-luminous 1. Put in order all the parts of the electromagnetic spectrum starting with the least energetic. radio, microwave, infrared, visible light, UV light, x-ray and gamma rays. 2. Match each electromagnetic wave from column A with the term from column B. Column A Column B X-rays medical imaging radar ultraviolet light vitamin D telecommunications radio waves telecommunication TV remote control Infrared light tv remote control vitamin D microwaves radar cancer treatment gamma rays cancer treatment theatre/concert effects visible light theatre concert effects medical imaging 3. List the seven colours that are identified in the visible spectrum of white light. Red, orange, yellow, green, blue, indigo and violet 4. Complete the following diagram by adding in the reflected ray; also label the mirror, the normal, and the angle of incidence. 5. Clearly state the two laws of reflection. a) angle of incidence equals angle of reflection b) incident ray, reflective ray and normal are all on the smae plane. 6. When light is traveling from a faster medium to a slower medium how does the light bend (towards or away from the normal)? towards the normal 7. With concave mirrors the image you get depends on the position of the object, but with a convex mirror it does not, what are the FOUR characteristics of an image formed by a convex mirror? Size, Attitude, Location and Type 8. Sometimes the image in a concave mirror is upright and sometimes it is inverted. a) Where must you be to see an upright image of yourself? in between the focal point and the mirror b) Where must you be to see an inverted image of yourself? beyond the focal point but not on the focal point 9. Why are convex mirrors placed on sharp turns in parking garages? virtual image is small and there is a large field of view. 10. Draw a suitable diagram to show what will happen if light travels from a slower medium to a faster medium. 11. Under what conditions will light totally internally reflect. Light is travelling from a slow to fast medium and it bends past the critical angle and then it reflects back into the slow medium. 12. What is refraction? When a ray of light bends as it travels from one medium to another. The speed of the light makes it bend.  Complete the following table: Information Angle of Angle of Incidence Reflection Angle between the reflected 47o ray and the normal is 47o Angle between the incident 26o 26o ray and the reflected ray is 52o 52/2 = 26 Angle between the incident 76o 76o ray and a plane mirror is 14o 90 - 14 = 76 The incident ray comes in 0o 0o along the normal 13. What are the primary light colours? red blue green 14. What are the secondary light colours? cyan, yellow, magenta 15. If rays of red, green and blue light overlap what would you see? white 16. What colours of stage lights cannot be used to make a green dress appear black? red Why?_______________________________________________________________________ ___________________________________________________________________________ 17. If a green filter followed by a yellow filter is used with white light. What would you see? ____________________________________________________________________ 18. What is the complementary colour to the primary light colour red? _____________ 19. What colour filter would need to be placed in front of an object in order that a cyan object will appear blue? ______________________ Ray Diagrams for Mirrors 20. Draw the following ray diagrams and state the characteristics of the image. Ray Diagrams for Lenses 21. Draw the following ray diagrams and state the characteristics of the image.
