Unit 5 Lesson 3 Quiz
1. B
A is incorrect because the statement is true. Electromagnetic waves do travel at the speed of light.
B is correct because the statement is false. Electromagnetic waves do not need a medium to travel
through.
C is incorrect because the statement is true. Different wavelengths of light are interpreted by our eyes
as different colors.
D is incorrect because the statement is true. The transfer of energy as electromagnetic waves is
called electromagnetic radiation.
2. A
A is correct because the statement is false. Black light, not white light, is the absence of color.
B is incorrect because the statement is true. Higher-frequency electromagnetic waves have more
energy.
C is incorrect because the statement is true. The sun radiates several different types of
electromagnetic energy.
D is incorrect because the statement is true. The frequency of an electromagnetic wave is related to
its wavelength.
3. B
A is incorrect because gamma rays, not radio waves, have the shortest wavelength (highest
frequency).
B is correct because gamma rays have the shortest wavelength (highest frequency).
C is incorrect because gamma rays, not infrared waves, have the shortest wavelength (highest
frequency).
D is incorrect because gamma rays, not ultraviolet waves, have the shortest wavelength (highest
frequency).
4. B
A is incorrect because all electromagnetic waves travel at the same speed, which is the speed of
light.
B is correct because the higher the frequency, the higher the energy. If delta rays have a higher
frequency than gamma rays have, then delta rays would have more energy.
C is incorrect because if delta rays have a higher frequency than gamma rays have, then delta waves
would have a shorter wavelength.
D is incorrect because if delta rays have a higher frequency than gamma rays have, then delta waves
would have a shorter, not longer, wavelength.
5. D
A is incorrect because visible light waves, not microwaves, have the highest frequency and thus the
most energy.
B is incorrect because visible light waves, not radio waves, have the highest frequency and thus the
most energy.
C is incorrect because visible light waves, not infrared waves, have the highest frequency and thus
the most energy.
D is correct because visible light waves have the highest frequency and thus the most energy.
