What determines the color of an opaque object?
The color of an opaque object is the color of the light it absorbs.
The color of an opaque object is the color of the light it transmits.
The color of an opaque object is the color of the light it reflects.
The color of an an opaque object is the color of the light it refracts.
What determines the color of a transparent or translucent object?
The color of these objects is the color of the light they absorbs.
The color of these objects is the color of the light they transmits.
The color of these objects is the color of the light they reflects.
The color of these objects is the color of the light they refracts.
Why is an apple red?
White light strikes it and the red frequency is reflected, while all others are absorbed.
White light strikes it and the red frequency is absorbed, while all others are reflected.
Why does blue glass appear blue?
White light strikes it and it reflects blue frequencies and transmits all others.
White light strikes it and it allows only blue frequencies to be transmitted.
All blue light must strike the glass for it to appear blue.
What would happen if you looked at a green leaf through a red color filter?
The color filter would not affect the color of the leaf. It would still look green through the filter.
Only red frequencies are let through the color filter, so the leaf would appear red.
No green frequencies are let through the red filter, so they are not there for the leaf to reflect. It would appear black as a result.
How do colors of light combine? (Select all that are true).
When the three primary colors of light are combined equally, they produce white light.
The three primary colors of light are red, green and blue.
In different proportions, they can produce different other colors.
The secondary colors of light a red, magenta and cyan.
Select all that are true of mixing pigments.
When combined in equal proportions, the three primary pigments create black.
By combining pigments in varying amounts, you can create different colors.
The primary colors of pigments are yellow, cyan and magenta.
As you combine more pigments, less light is reflected and more is absorbed, making the mixture darker.
