- 1MediumAny physical substance in which energy can be transferred ( air , water )
- 2Radiationa method of energy transfer that does not require a medium. Example: neon lights
- 3Electromagnetic Wavesa wave that has both electric and magnetic waves parts. Does not require a medium, travels at the speed of light
- 4Speed of Light= 3.00 x 10^8 m/s
- 5Light Raya line on a diagram representing the direction and path that the light is travelling
- 6Geometric OpticsThe use of light rays to determine how light behaves when it strikes an object
- 7Incident Lightlight emitted from a source that strikes an object
- 8Transparenta material that transmits all incident light
- 9Translucenta material that transmits some incident light and refracts or absorbs the rest
- 10Opaquea material that does not transmit any incident light but absorbs or reflects all light
- 11imagereproduction of an object through the use of light
- 12mirrorany polished surface reflecting an image
- 13Reflectionthe bouncing back of light from a source / surface
- 14plane mirrorflat mirror
- 15incident raythe incoming ray that strikes a surface
- 16reflected raythe ray that bounces off a reflective surface
- 17Normalthe perpendicular line to the mirror surface
- 18Perpendicularat right angles
- 19Angle of incidencethe angle between the incident ray and the normal
- 20Angle of reflectionthe angle between the reflected ray and the normal
- 21specular reflectionreflection of light off a smooth surface
- 22diffuse reflectionreflection of light off irregular or dull surfaces
- 23virtual imagean image coming from an apparent light source. light is not bouncing off or coming from the image location
- 24optic centerthe point at the exact center of the lens
- 25principle focusthe point on the principle axis where the light rays converge
- 26luminouscan be seen because they produce their own light
ex: the sun, a light bulb - 27Non luminouscan be seen because they reflect light
ex: the moon, paper - 28what is the significance of Sir Isaac Newton?Sir Isaac Newton was the first person to separate white light into the visible spectrum
- 29what is the order of the colours in the visible spectrumRed Orange Yellow Green Blue Indigo Viloet
- 30What are the 2 laws of reflection1) the angle of icidence equals the angle of reflection
2) the incident ray, the normal, and the reflected ray all line in the same plane - 31How can you locate an image in a concave mirror if : the object is beyond C? *Draw Diagram*The image will be :
L : between C and F
O : inverted
S : smaller
T : Real - 32How can you locate an image in a concave mirror if : the object is located at C? *Draw Diagram*The image will be
L: at C
O: inverted
S: same size
T: real - 33How can you locate an image in a concave mirror if : the object is located in front of C *Draw Diagram*The image will be
L: beyond C
O: inverted
S: larger
T: real - 34How can you locate an image in a concave mirror if : the object is in front of F *Draw Diagram*the image will be:
L: behind the mirror
O: upright
S: larger
T: virtual - 35How is light produced by: incandescencethe production of light from a high temperature. Example : Candle
- 36How is light produced by: Electric Dischargethe production of light by passing an electric current through a gas
- 37How is light produced by: phosphorescencethe production of light as a result of the absorption of high energy ultra violet rays resulting in the emission of low energy visible light over an extended period of time. Example : Glow in the dark toys
- 38How is light produced by: FlourescenceThe immediate emission of light as a result of the absorption of ultra violet light Example : Fluorescent light
- 39How is light produced by: ChemiluminescenceThe production of light as a result of a chemical reaction with little to no heat produced. Example: Glow sticks
- 40How is light produced by: BioluminescenceThe production of light in organisms as a result of a chemical reaction with little or no heat produced. Example: Firefly
- 41How is light produced by: Triboluminescencethe production of light as a result of scratching crushing or rubbing certain crystals. Example: striking 2 sugar cubes
- 42How is light produced by: LED's(Light Emitting Diodes) produce light as a result of an electric current flpwing through semi conductors
- 43How is light produced by: LASER's( Light Amplification by Stimulated Emission of Radiation) produce EM waves of exactly the same energy level
- 44Draw a diagram of an actual mirror and a scientific mirror...
- 45draw a diagram of reflected rays in a plane mirror...
- 46what does LOST stand for?Location
Orientation
Size
Type - 47What does C,F,V stand forCenter of curvature
Focal point
Vertex - 48how do you locate an image in a convex mirror?the image will be :
L : behind the mirror
O: upright
S: smaller
T: virtual - 49what is the equation for the index of refraction?N= C/V
- 50how can you rearrange the index of refraction formula to find the speed of light in a medium?V= C/N
- 51what does NCV stand for (index of refraction terms)N= index of refraction
C= speed of light in a vacuum
V= Speed of light n a medium - 52what are 3 characteristic of converging lenses? + Draw a diagram1) thickest in the middle
2) used to correct far farsightedness
3) makes light rays converge - 53what are 3 characteristics of diverging lenses? + draw a diagram1) thinnest in the middle
2) used to correct nearsightedness
3) causes light rays to diverge
