CTS Exam AVIXA Questions with Correct Solutions| Latest Update Graded A+
Dispersion Light is made up of different colors, each with a specific frequency. These
frequency differences cause light to refract at different angles when travelling through a
medium
Reflection Light bouncing off a smooth surface at the same angle it hit the surface
Scattering Scattering occurs when light hits a textured surface, the incoming light waves get
reflected in multiple angles because the surface is uneven.
Light being reflected at various angles when bouncing off a rough surface
Absorption Light being consumed when hitting darker colors
Inverse Square Law and Light The inverse square law states that as you move farther away
from a light source the brightness of the light at the viewing point will diminish. Moving closer
to the light source, the light will become apparently brighter.
As distance is doubled, the illumination of light is quartered.
As distance is doubled, the surface area of light quadrupled.
Three attributes that describe color Hue, Chroma, Grayscale
Hue Hue is the attribute of a color that represents a red, a purple, a green, etc.
Grayscale Grayscale is the brightness and darkness of a color.
Chrome Chroma is the saturation, or intensity, of a specific color
, Color Temperature Color temperature is the approximate quantification of the color of
"white" light, as rated on a numerical scale. Low color temperature light (~2000K) has a warm
(red-ish) look while light with a high color temperature (~6000K) has a colder (blue-ish)
appearance.
ELS or Ellipsoidal Reflective Spotlight -Focusable spotlight
-Used when control of light is important
-Range of focal lengths
Long looking light
Parabolic Aluminized Reflector Light -"Wash" luminaire
-Covers large areas of stage from a distance
-Difficult to control in projection environment
Short circle cylinder light
Key Light, Fill Light, Back Light, Wall Wash Key Light: the brightest light on the subject
Fill Light: fills the dark spot created by the key light
Back Light: shines on the subject's shoulders and hair
Wall Wash: lights the background
Bandwidth A measure of the amount of data or signal that can pass through a system during
a given time interval.
