Wave Activity

This document discusses three types of waves: transverse waves, longitudinal waves, and surface waves. For transverse waves, a rope is vibrated up and down to create a pulse that moves perpendicular to the direction of the rope. For longitudinal waves, a coil spring is vibrated back and forth parallel to its length, causing compressions and rarefactions that propagate down the spring. For surface waves, tapping the surface of a basin of water creates pulses and periodic waves that set a paper boat floating on the surface into motion.

WAVE ACTIVITY

LET’S MAKE WAVES!

What are transverse waves?


Procedure:
A. Straighten the rope and place it above a long table. Hold one end of the rope and
vibrate it up and down. You would be able to observe a pulse. Draw two sketches
of the rope showing the motion of the pulse at three subsequent instances
(snapshots at two different times). Draw an arrow to represent the direction of the
pulse’s motion.

Time 2

Guide Question
1 .What is the source of wave pulse?

B. Tie one end of the rope on a rigid and fixed object ( table, door knob). Attach a
colored ribbon on one par5t of the rope. You may use adhesive tape to fix the
ribbon. Make a wave by continuously vibrating the end of the rope with quick up
and down movements of your hand. Draw the waveform or the shape of the
wave that you have created in the box.

Guide Question:
1.Describe the vibration of the colored ribbon. How does it moves as waves pass by?
Does it move in the same direction as the wave?

What is longitudinal waves?


Procedure:
1. Connect one end of a long table to a wall. Place coil spring on top of table. Attach
one end of the coil spring to the wall while you hold the other end.
2. Do not lift the soil spring. Ask a friend to vibrate the end of the coil spring by
doing a back-and-forth motion parallel to the length of the spring. Observe the
waves along the coil spring. Draw how the coil spring looks like as you move it
back-and-forth in the box.
3. Attach a colored ribbon 0onm one part of the coil spring. You may use adhesive
tape to fix the ribbon. Ask a friend to vibrate the coil spring back-and-forth while
you observe the motion of the colored ribbon. Remember that the colored ribbon
serves as a marker of a chosen segment of the coil spring.
Guide Question:
1.Describe the vibration of the colored ribbon. How does it move as wave pass by?

What are surface waves?


Procedures:
1. Place a basin filled with water on top of a level table. Wait until the water become
still or motionless. Create a wave pulse by tapping the surface of the water with
your index finger and observe the direction of travel of the wave pulse. Tap the
surface of the water at regular intervals to create periodic waves. View the waves
from above and draw the pattern that you see in the box. In your drawing, mark
the source of the disturbance.

2. Wait for the water to become still before you place your paper boat on the
surface. Create periodic waves and observe what happens to your paper boat.
Guide Questions:
1.Do the waves set the paper boat into motion? What is required to set an object into
motion?

2. If you exert more energy in creating periodic waves by tapping the surface with
greater strength, how does this affect the movement of the surface boat?
