Lesson 4 Quiz
1. C
2. D
3. A
4. B
5. C
1. C
A is incorrect because it is possible to see clearly through pure air. It is a transparent, not a
translucent, material.
B is incorrect because it is possible to see clearly through clear plastic. It is a transparent, not a
translucent, material.
C is correct because only blurry images can be seen through frosted glass. Translucent materials
scatter light.
D is incorrect because light cannot pass through construction paper. It is opaque, not translucent.
2. D
A is incorrect because light would speed up while going from a solid to a gas.
B is incorrect because light would speed up while going from a solid to a liquid.
C is incorrect because light would speed up while going from a solid to a gas.
D is correct because light slows down while going from a vacuum to any type of matter.
3. A
A is correct because light with the shortest wavelength refracts the most. Of the four colors listed,
blue light has the shortest wavelength.
B is incorrect because light with the shortest wavelength refracts the most. Green light has a longer
wavelength than blue light does.
C is incorrect because light with the shortest wavelength refracts the most. Orange light has a longer
wavelength than blue light does.
D is incorrect because light with the shortest wavelength refracts the most. Red light has a longer
wavelength than blue light does.
4. B
A is incorrect because the longest wavelengths of light refract the least. Of the colors listed, red is the
longest wavelength, and so it must be color 1, not color 4.
B is correct because the shortest wavelengths of light refract the most. Of the colors listed, blue has
the shortest wavelength, and so it must be color 4.
C is incorrect because the shortest wavelengths of light refract the most. Color 4 could not be green
light, because its wavelength is longer than the wavelength of blue light.
D is incorrect because the shortest wavelengths of light refract the most. Color 4 could not be yellow
light, because its wavelength is longer than the wavelength of blue light.
5. C
A is incorrect because the surface absorbs all colors except green. It would have to absorb all colors,
including green, in order to appear black.
B is incorrect because the surface reflects only green. It would have to reflect other colors in order to
appear brown.
C is correct because the surface reflects green. When the combination of blue and green light strikes
it, the surface will absorb the blue light and reflect the green light and appear green.
D is incorrect because the surface reflects only green light. It would have to reflect all colors.
