Final Exam

Question 1

metamerism

Answer 1

two colors match if they have the same tristimulus values for a given illuminant and observers

Question 2

Visible spectrum

Answer 2

400-700 nm

Question 3

White light

Answer 3

all colors/wavelengths combined

Question 4

wave

Answer 4

disturbances of particles, the passage of light, heat, sound etc

Question 5

particles

Answer 5

tiny balls/pieces that make up photons, that make up light

Question 6

refraction

Answer 6

bending of a wave, shorter wavelengths refract more

Question 7

reflection

Answer 7

incident light/wavelengths go back at the same angle it hit

Question 8

absorption

Answer 8

wavelength energy is taken into object

Question 9

transmission

Answer 9

light/wavelength goes THROUGH the object (transparency may occur)

Question 10

photon

Answer 10

particles that light is made of

Question 11

radiant flux

Answer 11

radiant energy emitted, reflected, transmitted (by and object) per unit of time

Question 12

λ

Answer 12

the length of a wavelength, distance between 2 peaks or valleys

Question 13

wavelength and frequency (energy) relationship

Answer 13

inverse

Question 14

reflectance factor curve

Answer 14

shows what wavelengths/colors bounce back from object in a graph

Question 15

blackbody

Answer 15

the most efficient absorber and best light source (emits over wide energy band)

Question 16

law of reflection

Answer 16

angle of incidence = angle of reflection

Question 17

scattering

Answer 17

when light bounces off particles in many directions (creates color of the sky)

Question 18

The Eye

Answer 18

cornea > pupil > lens > retina > fovea > optic nerve > brain

Question 19

cones

Answer 19

for color, see RGB, mostly located in fovea, makes humans trichromats

Question 20

colorblindness

Answer 20

just color deficient, effects men more often than women

Question 21

rods

Answer 21

see in lowlight, there are more than cones

Question 22

3 things needed to classify color

Answer 22

hue, saturation, lightness

Question 23

hue

Answer 23

traditional color name of wavelength

Question 24

saturation

Answer 24

purity of the color

Question 25

lightness/brightness/value

Answer 25

lightness or darkness in a color

Question 26

Additive System

Answer 26

RGB

Question 27

Subtractive System

Answer 27

CMYK

Question 28

Ostwald System

Answer 28
