1. The document contains answers to questions about sound waves and how they cause salt grains or other objects to bounce up and down. 2. Sound waves are produced as vibrations when a small can is tapped forcefully, causing the plastic top of a larger can to also vibrate. 3. Longitudinal waves, including sound waves, involve alternating compressions and rarefactions that cause the medium, such as air, to vibrate parallel to the direction of wave propagation.

1. Answers to Questions:
Q1. The salt bounced up and down.
Q2.When the small can is tapped loudly or forcefully.
Q3.Sound was produced when the small can is tapped.
Yes the salt bounced
up and down the plastic top while tapping the small can.
Q4.The sound produced in the small can made the plast
ic top of the large canvibrate making the salt bounce up
and down.
Q5.Sound waves are vibrations of air particles
Q6.The rock salt bounced higher the loudness of the
sound is increased.

2. Q7. The amplitude of the wave.
Q8. The other colored beads collided with the blue bead
Q9. Yes
Q10. Yes
Q11.Sound wave is classified as a longitudinal wave

3. With the compressions and rarefactions, what you were
Able to produce is called a longitudinal wave.
Longitudinal waves are waves that are usually created by pu
lling and pushing the
material or medium just like in the slinky (Figure 6). Alternat
ing compressions and
rarefactions are observed. These compressions and rarefacti
ons move along with
the direction of the pushing and pulling activity of the mater
ial or medium. Thus, the
wave moves parallel to the motion of material or the particle
s of the medium. This is
known as a longitudinal wave.
