|
Addition model of color |
The theory that explains what happens when coloured lights are mixed together to produce other colors |
What happens when you mix colors |
|
|
Angle of incidence |
Angle of the incoming ray and the normal |
Angle of blank ray and blank |
|
|
Angle of reflection |
Angle between the reflected ray and the normal |
Space between blank ray and normal |
|
|
Bioluminescence |
Light omitted from a living organism as a result of naturally occurring chemical reaction inside the organism |
Chemicals react in a living organism result in |
|
|
Concave lens |
Price of transparent material that is thinner in the middle then in the edge marking it curve in |
|
|
|
Concave mirror |
Reflecting surface that is curved inward that makes light rays come together |
|
|
|
Convex lens |
Price of transparent material that is thicker in the middle then the edge it is curved outward |
|
|
|
Diffuse reflection |
Reflection of light off an uneven surface which results in light scattering |
|
|
|
Focal point |
The point at which the light rays form an image come together |
|
|
|
Illuminance |
The amount of light arriving at one place per unit area |
|
|
|
Incident ray |
Ray of light that arrives at a mirror or enters a substance |
|
|
|
Law of reflection |
Angle of incidence of a wave hitting equals the amount of reflection |
|
|
|
Lens |
Price of glass or other transparent material that either brings together or spreads out light rays passing through it |
|
|
|
Luminance intensity |
The light that is emitted from the surface of an object such as a light |
|
|
|
Luminous |
Objects that give out light sun fire light bulb |
|
|
|
Lens |
Price of glass or other transparent material that either brings together or spreads out light rays passing through it |
|
|
|
Luminance intensity |
The light that is emitted from the surface of an object such as a light |
|
|
|
Luminous |
Objects that give out light sun fire light bulb |
|
|
|
Electromagnetic spectrum in order |
Gamma rays, x rays, ultra violet, visible light, infrared, micro waves, radio waves |
|
|
|
Real image |
An image that appears in the same side of a mirror as the object light rays pass through the object location and the image can be projected onto a screen ex projector or image produced on retina |
|
|
|
Virtual image |
When the light rays coming from an object don't meet but spear to meet when turned backwards it is on a plain mirror, ex your reflection in a mirror |
|
|
|
Property of a wave |
Wave property of light shows property of wave, form of energy, moves in every direction, wave lengths is the distance between the top of two waves |
|
|
|
Properties of light |
Consists of color which can split apart, light moves out ward from the source in every direction, form of energy, our eyes detect it, moves in straight lines, can be reflected and refracted, illuminance decreases with distance from the source |
|
|
|
Primary colors |
Red green and blue |
|
|
|
Secondary colours made by |
Red and blue make magenta Red and green make yellow Green and blue make cyan Green blue and red make white All colours make black |
|
|
|
What is the difference between reflection and refraction |
Refraction is when light ends around an object Ex pencil looks bent in water Reflection is when light hits an object and bounces off Ex when you look in a mirror you see your reflection |
|
|
|
What is umbra and panimbra |
Panumbra is the partially shaded region of a shadow Umbra is the fully shaded region of a shadow |
|
|
|
What is opaque translucent and transparent |
Opaque is an object that doesn't let light through Translucent is when it lets a little light through Transparent is when it lets all light through |
|
|
|
How is the human eye similar to a camera |
Pupil - aperture Retina - film Lens - lens Ciliary muscles - focus ring |
|
|
|
Subtraction model of color |
When coloured pigments are mixed together each primary color of pigment subtracts a primary color of light and reflects the other two |
|
|
|
Non luminous |
Objects that do not give off light but may reflect most objects are not ex moon |
|
|
|
Speculate reflection |
Reflection off a smooth surface |
|
