1. How fast is a wave moving if it has a wavelength of 4.0 m and
a frequency of 4 Hz? - correct answer -16 m/s
2. A long, taut string on a guitar is plucked. The wave that travels
down its length is: - correct answer -transverse
3. Let's take the speed of sound to be 340 m/s. What would be
the length of the pipe in a pipe organ that produces a note with
a pitch of 170 Hz? - correct answer -1 m
4. What is the frequency of the lowest pitch the human ear can
hear? - correct answer -20 Hz
5. Which of the following is an observation we can make about
pipes in a pipe organ? - correct answer -The length of the

pipe is inversely proportional to the frequency of the sound it
produces.
6. When two waves, each with identical frequencies and an
amplitude of 4 cm, interact with each other at the same point,
which of the following happens? - correct answer -Without
knowing the timing of the waves, we can't say anything.
7. An electromagnetic wave cannot arise directly from which of
the following? - correct answer -A sound wave
8. Which of the following is the best statement regarding the
propagation of light through space? - correct answer -
Electromagnetic waves seem to travel through a complete
vacuum.
9. The nature of an electromagnetic wave is that: - correct
answer -the electric field is perpendicular to the magnetic field
and both are perpendicular to the direction of propagation.

10. Taking the speed of light as being equal to 3 x108m/s, if an
electromagnetic wave has a frequency of 6 x 108 Hz what is its
wavelength? - correct answer -0.5 m
11. Looking in the night sky, you notice four different colored
stars. Ignoring any influence of the Doppler effect and thus
based on the color alone, which star has the hottest surface? -
correct answer -the light blue one
12. The Doppler Effect is NOT observed where the following
occurs: - correct answer -c) Both the observer and the source
are moving at the same velocity.
13. You are driving 15 mph above the speed limit when a police
officer aims a radar gun at your car to measure its speed. Your
car is moving away from the officer. If the frequency of the
radar wave from the gun is 10,525 MHz, what can we say
about the frequency of the radar wave reflected off your car? -
correct answer -it will be lower than 10,525 MHz
14. Short-wavelength ultraviolet light and gamma rays don't
travel very far through the Earth's atmosphere before being
absorbed. Based on this, which of the following would you
