Longitudinal Waves Lab Report

The Wave, by Todd Strasser, is a novel about a school-wide experiment about how the German people could have followed Hitler and the Nazis. Two characters Laurie Saunders and Robert Billings showed a dramatic change in their actions, popularity, and their emotions from the Wave experiment. Together they had a huge impact at their school, Gordon High.

A sound wave is a disturbance that repeats regularly in space and time and that transmits energy from one place to another with no transfer of matter. In Activity 2 on page 8 we had to model sound waves using an instrument. In our class we used a flute as the example and when the person blew into it, sound waves were produced. As they blew and changed the volume and pitch the sound waves changed. A sound wave is created when something vibrates. When something vibrates, longitudinal waves are created which we can hear. A longitudinal wave is a wave that transfers energy through compressions and rarefactions in the material that the wave travels which are all parts of a sound wave. In Activity 2 it states in some parts of the wave, the air molecules

Doubts of the the wave erupted for Laurie because of the insight her mother gave her about the wave. Lauries mother explained how no one will be able to express themselves or be independent while participating in the experiment. She got lost in the unity part of the wave and didn't see what was really happening until it was pointed out by her

Step 3: Then place your left on the right hang at the level were your right breast is, then take your right hand around the front and place your right hand the end of the left hang.

Wiggle your fingers and toes. Open your hands...then close them... and open them once again.

The waves were beginning to be pulled back similar to that of a metal being attracted to the magnet. It was not stopping, the waves were continuously being pulled

From the start position, stand with your feet shoulder-width apart with your arms outstretched, forming a 180 degree angle. Inhale as you lift your left leg up, bent at the knee. Exhale as you bring the left leg back into a front lunge. Your right leg should form a 90-degree angle at the knee, and your right thigh should come as close to parallel to the ground as possible. As you lower into the lunge, bring both arms out to your sides at shoulder height. Hold for two seconds, then rise and return to standing, bringing legs and arms back to starting

Sound is a wave, and a wave can be remembered as a medium, carrying energy from one point to another. The sound wave has a resemblance of a slinky in its nature, for many reasons. The disturbance goes from one place to another, carried by the medium. Typically, the medium will carry energy through the air, although it could be any substance like water and steel. There is an original source of the wave; anything from someone’s vibrating vocal chords, or a tuning fork. Then, the sound is transported through the medium through particle-to-particle interaction. If the sound wave is moving through the

The interactive activity found on the link, pictured below, is something that I found to be very useful. It gives you the opportunity to visually see the differences within the waves when you change the different aspects of them. You can change one component at a time, or all at once and have the ability to compare and contrast what each of them visually look like.

Based on the data shown by the graph, wave A is representing an s-wave. If you look at wave A on the graph, you see that wave A comes to a sudden stop when it reaches a depth of 2900 km below the Earth's surface. This is because whenever an s-wave hits a liquid substance or barrier,

To begin the steps process, grab a ball about the size of a basketball with two hands. For right-handers put your left hand on the left side and your right hand on the side facing you. Left-handers are the opposite,

The sound waves are produced by a random oscillating crystal, and are inaudible to humans. A instrument called a

The red bar on the left acts as the driving piston. If it moves in a sinusoidal manner from left to right, then the wave that is produced will be a sinusoidal wave. Since the wave is sinusoidal, the wavelength, amplitude and frequency are constant. This is seen in nature as a tuning fork, which produces a periodic sound wave. In a one dimensional tube as shown above, each particle undergoes simple harmonic motion. The volume that is contained in one wavelength also undergoes this same motion. We can represent the displacement of this volume as:
