1. Marsha and woman playing volleyball in the park Shahrukh southern African nation. It appears that the accident was not unexpected. Woman hit volley that crashed into the pond, which receives water from the Amazon River. Both remembered the mother otter and then try to stretch the limbs, you can not reach out to the store. Both remembered the science. He may say to each other that
I came here I thought that if the feet hit the water regularly so the wave can take the ball to the opposite side has certainly not her
woman: Do you think this concept! It does not work You have to stick around To throw the ball at the spot of the ball, then it will be up to the shore opposite the
students think it is? Stating the reason
was because the woman is the wave that causes the particles that make it up and down. Ball like particles If there is not any pressure to do more to make the particles do not move. The Sri put the branch that is thrown away, adding to the pressure exerted on the particles tend to keep moving particles
2. Consider and answer the following questions:
2. What is the position of the ridge wave N, H, B
3. What is the position of the wave D, K
4. This wave amplifiers J equals 5 cm
5. In many ways this is a long wave. 2.5λ
6. 1 wavelength measures 0.2 meters or 20 centimeters
if the wave moves from position N to H, within two seconds,
7 seconds interval = 2
= 0.5 Hz frequency 8.
9. = wave speed of 0.1 m / s. Wilson
10. one ship anchored. Was hit by a wave, which has a speed of 30 meters per second. Crested waves away 150 meters, find time each wave runs the ship
needs to v = 30 m / s "λ" = 150 m for a period
of v = lambda / T
30 = 150 / T
T = 5 seconds
11. . in the wave motion. Flick the energy from one end of the rope to pass
to the other side of the ropes have shown that
energy 1. Live with the motion of the waves
transfer energy 2. After the wave passed
3. Power is transmitted before. wave to arrive
4. energy from waves to transfer the particles and the particles will move to the end of the rope
12. when the surface waves spread out. Object floating on the surface, there was a movement, however,
is still intact 1.
2. actions to increase and when the wave passed
by wave 3. Mobile
4. Moving forward, then backwards
from 13. Show the pulse at a time, which is moving to the left, you know. Over time point A and point B is a point on the spectrum, however, are moving
to the left AB 1. A and B, two points
2. A up, B down
to 3. A, B, up
to 4. A, B. down
14. wave does not need any kind of intermediaries in motion
a wave 1.
2. electromagnetic
waves in the rope 3.
4. a wave spring
15. The following text Which is correct
g-wave longitudinal direction of oscillation of particles intermediary in line with the direction of the wave, the wave
b. Transverse direction of oscillation of particles intermediaries perpendicular to the motion of the waves
c. Transverse wave and wave. there will be short-wave and long wave, the same
position. power transfer to the intermediary will have constant speed
1 and b 2 and b
3, b and 4. a, b, c, and d
16. in wave motion Which is correct
g waves to transmit power of
the message. Longitudinal wave and transverse wave is the oscillation of particles intermediaries alike
, but the direction of a different
value. Longitudinal wave and transverse wave with the vibration. particles of different
, but the direction of the waves as
1. a 2. b 3. c 4. and there were
17. I dip the pen stroke is 60 times in 2 minutes, wave running from one end of
the pen. to the surface of the container away 50 centimeters in 10 seconds,
the waves have wavelengths as jars of
4 cm,
6 cm
to 8 cm,
10 cm
wave springs 18. a periodic oscillation 0.005 seconds, moving at a speed of 2 cm / sec
him. Spring for a wavelength

19. surface wave coastal areas. Measure the highest and lowest positions between 1.50 meters and
a surface wave amplitude jar as
0.5 m
0.75 m

1.5 m
20 in wave motion. Flick the energy from one end of the rope is
conveyed to the other side of the rope. Show that the
energy transmitted along with the movement of the wave
energy transmitted after the wave passed,
the energy is transmitted to the mobile wave will arrive
from the waves to transfer energy to particles and the particles will move to the end of the rope

25. the following message. What was
