## Resource summary

### Question 1

Question
The color of an object we see is determined by the
• colors of light reflected by the object.
• frequencies of light absorbed by the object.
• colors of light shining on the object.
• frequencies of light reflected by the object.
• all of the above

### Question 2

Question
Sunlight contains all colors of light, but much of it is
• orange.
• blue.
• violet.
• yellow.
• red.

### Question 3

Question
Light shines on a pane of green glass and a pane of clear glass. The temperature will be higher in
• the clear glass.
• the green glass.
• Neither, it will be the same in each.

### Question 4

Question
Colors seen on TV result from color
• subtraction.
• none of the above

### Question 5

Question
Different colors of light correspond to different light
• frequencies.
• polarities.
• intensities.
• velocities.
• none of the above

### Question 6

Question
When blue and yellow paints are mixed together, the result is green. The reason for this is that
• blue and yellow are complementary colors.
• yellow pigments absorb green light and reflect all the others.
• blue reflects only blue light, and yellow reflects almost all colors of light.
• between blue and yellow pigments, all colors are absorbed except green.
• blue absorbs yellow light and yellow absorbs blue light.

### Question 7

Question
Magenta light is really a mixture of
• red and yellow light.
• red and cyan light.
• yellow and green light.
• red and blue light.
• none of the above

### Question 8

Question
The color of an opaque object is determined by the light that is
• absorbed.
• reflected.
• transmitted.
• all of the above
• none of the above

### Question 9

Question
If sunlight were green instead of white, the most comfortable color to wear on a hot day would be
• yellow.
• blue.
• green.
• magenta.
• none of the above

### Question 10

Question
If molecules in the sky scattered orange light instead of blue light, sunsets would be colored
• yellow.
• blue.
• green.
• orange.
• none of the above

### Question 11

Question
If the atmosphere were 50 times thicker than it now is, the sun would appear
• blue-violet.
• orange-green.
• red-orange.
• green-blue.
• none of the above

### Question 12

Question
The reason the sky is blue is that air molecules
• are blue.
• reflect blue light.
• absorb yellow light.
• absorb and then reemit blue light, scattering it in all directions.
• absorb green light.

### Question 13

Question
Sunsets are red because
• the longest path of sunlight through the atmosphere is at sunset or sunrise.
• a lot of high-frequency light is scattered by the atmosphere.
• blue light from the sun is scattered by Earth's atmosphere.
• all of the above
• none of the above

### Question 14

Question
The true color of water is
• clear.
• greenish blue.
• sky blue.
• green.
• white.

### Question 15

Question
The cyan color of ocean water is evidence that the water absorbs
• yellow.
• green.
• orange.
• blue.
• red.

### Question 16

Question
When a sample of an element is heated until it glows, the color it gives off is
• a continuous band of color.
• a composite of many frequencies of light.
• a single frequency of light.

### Question 17

Question
The colors of light emitted by incandescent gases show the
• absorbing qualities of gas.
• polarization of atoms in the gas.
• relative masses of atoms in the gas.
• identities of atoms in the gas.

### Question 18

Question
Spectral lines in a line spectrum take the shape of lines because the
• atoms that emit the light vibrate along parallel lines.
• light emitted aligns with the gravitational field.
• slit of the spectroscope is itself a line opening.
• light is polarized.

### Question 19

Question
The three primary colors of light for additive color mixing are
• red, green, and blue.
• yellow, green, and blue.
• red, yellow, and blue.
• red, yellow, and green.
• yellow, cyan, and red.

### Question 20

Question
When red and green light shine on a white sheet, the resulting color is
• blue.
• green.
• yellow.
• magenta.
• cyan.

### Question 21

Question
The complementary color of blue is
• yellow.
• cyan.
• violet.
• green.
• magenta.

### Question 22

Question
The colored dots that make up the color on a TV screen are
• red, blue, and yellow.
• red, blue, and green.
• magenta, cyan, and yellow.
• red, green, and yellow.
• yellow, blue, and green.

### Question 23

Question
A photograph of your favorite person's yellow sweater shows as what color on the negative?
• Green
• Orange
• Red
• Blue
• Yellow
