Question

1. The time needed for a wave to make one complete cycle is called the wave's

a. frequency

b. period

c. wavelength

d. velocity

e. amplitude

2. A skipper on a boat notices wave crests passing the anchor chain every 5 seconds. The skipper estimates the distance between crests in 15 m. What is the speed of the water wave?

a. 2m/s

b. 3m/s

c. 5m/s

d. 15m/s

e. 75m/s

3. A standing wave occurs when

a. a high frequency wave meets a low frequency wave

b. the incident wave moves into a new medium

c. the medium is standing still

d. there is a difference between new and reflected waves

5. Your amplifier is playing a 200Hz tone. When you double the amplitude(loudness), what happens to the speed of the sound and the frequency?

a. v doubles, f stays the same

b. v doubles, f also doubles

c. v stays the same, and f doubles

d. v and f both stay the same

e. v and f both descrease

5. A standing wave is created ina string because

a. the speed of propagation of waves is so slow that it appears "standing"

b. an iscolation with a higher amplitude catches has nowhere to go, as it stops

c. As the vibration reaches the end of the string it reflects and, while traveling back, interferes with the vibration, traveling forward

e. strings naturally form standing waves

6. Waves transmiot from one place to another

a. energy

b. mass

c. amplitude

d. moonium

7. if you blow air over the top of a bottle correctly, the air in the bottle will resonate. What happens to the frequency of the sound if water is added from the bottle?

a. gets lower

b. gets higher

c. stays the same

8. If the frequency of waves traveling through a meduim is halved, the wavelength

a. doubles

b. stays the same

c. is cut in half

d. is quadrupled

9. An ambulance has a siren with a frequency of 800Hz. You would hear a frequency higher than 800Hz if

a. the ambulence moved towards you

b. you moved toward the ambulence

c. the ambulence moved away from you

d. in both cases A and B

e. in all 3 cases A, B, and C

Explanation / Answer

1) b.period

2)wave length=15m,frequency=1/5 s-1

   velocity=15x1/5=3m/s

3) not clear(standing wave occur when tow waves of same frequency superimpose)

4) d.both stay same

5)c is the correct option

6)a)Energy

7) c)stay same

8) a)doubles

9) both A and B are correct
