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 / 0.001 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? 331 + 0.6 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 = 331 + 0.6 x 2 = 332.2 m/s v = f x λ 332.2 = 200Hz x λ λ = 1.66 m
