Light and Color
What was Newton’s theory of light?
Light is made up of streams of particles
A mirror with a flat reflecting surface is called?
Plane Mirror
What is the key symbol of Secondary focal point?
F’
Consist of wave trains that are either in phase or in a constant phase relationship at their point of origin
Coherent Light
What is the opposite to matter
Antimatter.
Primary colors of light
Red, green, blue
Of the varius kinds of curved mirrors, wich kind of mirror is the most important?
Spherical mirrors
What is the key symbol for Principal focal point?
F
Sideward emission of light by illuminated molecules or particles is called...
scattering
TRUE or False. You must touch an object in order to apply force to it.
false. There are forces that do not require the objects to touch in order to act on them, these are called non-contact forces. ex. magnetic forces.
What is the reality of mixing two subtractive primary pigments? All three?
Primary colors/ black
Wich law of reflection states that the angle of incidence is equal to the angle of reflection?
Wich law of reflection states that the angle of incidence is equal to the angle of reflection?
What is a meteríal that is resistant to the transmission of light waves?
Optical density
When iluminated by an overhead light source, the lens displays a pattern of alternating light and dark rings called..
Newtons rings or fringes
What does a manometer measures
pressure of a closed system.
What is the result of mixing all three primary colors?
White light
How does the ratio "hı/ho" is called?
Lateral magnification
What does the principle of reversibility says?
The path of a light ray subjected to reflection or refraction is traced in reverse by any ray coming along the path in the opposite direction
When a surface has no irregularities with height or depth exceeding a quarter wavelength of heght the surface is....
Optically flat.
If an object is in free fall, what is the only force that is acting upon that object?
Gravity
Three methods of additive mixing
-Send white light through a prism and block out unwanted frequencies
-Presenting different colors in rapid sequence to the eye
-Color printing/overlay
An arrow showing the direction of a wave front.
Ray
What does the principle of reversibility says?
The path of a light ray subjected to reflection or refraction is traced in reverse by any ray coming along the path in the opposite direction
Consist of wave trains that are either in phase or in a constant phase relationship at their point of origin
Coherent Light
What scientist said, "Give me a lever long enough and a place on which to rest it, and I shall move the world."
Archemedes
