14
The type of wave that oscillates perpendicular to
the direction the wave travels.

15
transverse
• Back to Jeopardy

16
A type of wave that does not need a medium

26
When a door is only slightly opened, sound will
pass from one room to another due to mainly

34
The unit for measuring the loudness of sound

35
Decibel (dB)
• Back toUnit Review Jeopardy

36
True or False The speed of sound is about 343 m/s

37
True
• Back to Jeopardy

38
True or False Sound waves are slower than light
waves

39
True
• Back to Jeopardy

40
True or False Sound waves travel faster in outer
space than in air.

41
False Sound depends on three things a vibrating
source to create the sound waves, a medium (such
as air) to carry the waves, and a receiver to
hear them. Sound waves can't travel through a
vacuum.
• Back to Jeopardy

42
Give the correct order from slowest to fastest
for the speed of sound through these three
media. water, air, wood

43
Some mediums are better at
conducting sound than others. Like all gasses,
air is a poor medium for sound waves. Liquids,
such as water, are better, and rigid, solid
substances, such as iron and stone, are even
better, while rubber, cork, and cotton are some
examples of poor conductors.
(slowest)Air, water, wood (fastest)
• Back to Jeopardy

44
As you decrease the temperature pressure of
air, does the speed of sound increase or
decrease?

45
Decreases!
• Back to Jeopardy

46
As the wavelength decreases, the frequency of a
wave ________________

47
increases
• Back to Jeopardy

48
As the loudness of a sound increases, the
amplitude of the wave ______________

49
increases
• Back to Jeopardy

50
The frequency increases when the source and the
observer approach each other and decreases when
they move apart.

51
The Doppler Effect
• Back to Jeopardy

52
Which of the following sounds has the shortest
wavelength? A)Thunder _at_ 75 hz B) a female soprano
singer _at_2000 hz C) a mans voice _at_ 500 hz

53
B) a female soprano singer _at_2000 hz
• Back to Jeopardy

54
What is the equation you would use to solve for
wavelength of a wave?
55
V / f l
• Back to Jeopardy

56
A wave made by dropping a ball in water has a
frequency of 2 Hz and a speed of 10 m/s. What is
the wavelength of this wave?

57
5 m

58
A tuning fork has a frequency of 200 hz and the
wavelength of sound produced is 10m. Calculate
the velocity of the wave.

59
2000 m/s

60
An ocean wave is moving toward the shore with a
velocity of 15m/s. If its frequency is 5hz, what
is the wavelegth?

61
3 m
• Back to Jeopardy

62
A rope is moved with a speed of 120 m/s. If the
length of the wave is 10 m, what is the frequency
of the wave?
