3 1-5 What is a wave?

4 1-5A What is a wave? A wave is a disturbance that travels through matter or space and time.

5 1-10 How can you calculate the wavelength of a wave if you know the frequency and velocity?

6 1-10A How can you calculate the wavelength of a wave if you know the frequency and velocity? v = λf So: λ = v / f

7 1-15 If a wave has a period of 0.001s what is its frequency?

8 1-15A If a wave has a period of 0.001s what is its frequency? f = 1/T f = 1 / s = 1,000 Hz

9 1-20 With a period of 0.02 s, and a velocity of 340m/s, what is the wavelength?

10 1-20A With a period of 0.02 s, and a velocity of 340m/s, what is the wavelength? v = λf v = λ/T 340 m/s = λ / 0.02 s λ = 340 m/s x 0.02 s λ = 6.8 m

11 1-25 If you have a wave with a wavelength of 10m, and a velocity of 200m/s, what is its period?

12 1-25A If you have a wave with a wavelength of 10m, and a velocity of 200m/s, what is its period? v = λf v/λ = f 200m/s / 10 m = 20 Hz f = 1/T T = 1/20Hz = 0.05 s

13 2-5 What is the approximate speed of sound?

14 2-5A What is the approximate speed of sound? 340 m/s

15 2-10 If a hummingbird flaps its wings 70 times / sec, what is the frequency of the sound?

16 2-10A If a hummingbird flaps its wings 70 times / sec, what is the frequency of the sound? 70 Hz

17 2-15 Two tones come from separate speakers. One has a frequency of 100Hz, the other is 103Hz. What is the frequency of the beat?

18 2-15A Two tones come from separate speakers. One has a frequency of 100Hz, the other is 103Hz. What is the frequency of the beat? 103Hz – 100Hz = 3 Hz

19 2-20 It is 40°C outside. What is the speed of sound?

20 2-20A It is 40°C outside. What is the speed of sound? x 40 = 355m/s

21 2-25 Type question here. Adjust size & position as necessary.

22 2-25A It is 2°C outside. What is the wavelength of a 200Hz tone? v = x 2 = m/s v = f x λ = 200Hz x λ λ = 1.66 m

23 3-5 Draw a standing wave

24 3-5A Draw a standing wave

25 3-10 What part of a standing wave does not move?

26 3-10A What part of a standing wave does not move? The Node

27 3-15 What part of a standing wave moves farthest from the center?

28 3-15A What part of a standing wave moves farthest from the center? The antinodes

29 3-20 If a standing wave has 4 antinodes, how many nodes does it have?

30 3-20A If a standing wave has 4 antinodes, how many nodes does it have? 5 nodes

31 3-25 If a string has a length of 1 m, and a standing wave with 3 nodes, what is the wavelength of the standing wave?

32 3-25A If a string has a length of 1 m, and a standing wave with 3 nodes, what is the wavelength of the standing wave? 1 m

33 4-5 What is the highest point of a wave?

34 4-5A What is the highest point of a wave? Crest

35 4-10 What is the lowest point of a wave?

36 4-10A What is the lowest point of a wave? Trough

37 4-15 The square of this will give you the intensity of sound.

38 4-15A The square of this will give you the intensity of sound. Amplitude

39 4-20 What is twice the distance from compression to rarefaction?

40 4-20A What is twice the distance from compression to rarefaction? Wavelength Compression Rarefaction λ

41 4-25 What travels in a wave?

42 4-25A What travels in a wave?

43 5-5 Name the TV show that has this theme song:

44 5-5A

45 5-10 Name this Instrument:

46 5-15 What is the name of the Minor League baseball team is based in Des Moines, Iowa?

47 5-15A What is the name of the Minor League baseball team is based in Des Moines, Iowa?

48 5-20 What was the name of Mr. Szarzak’s high school band?

49 5-20A What was the name of Mr. Szarzak’s high school band?

50 5-25 What is the best selling album of all time?
