To solve this task, we need to look at each picture and decide if it shows a Transverse Wave or a Longitudinal Wave.
Step 1: Understand the difference between the two types of waves.
*
Transverse Waves: The particles move up and down (perpendicular) while the wave moves forward. Think of shaking a rope up and down. You see high peaks and low valleys.
*
Longitudinal Waves: The particles move back and forth in the same direction the wave is traveling. Think of pushing and pulling a slinky. You see areas where the coils are squished together (compressions) and areas where they are spread out (rarefactions).
Step 2: Analyze each picture one by one.
*
Picture 1: This graph shows a line going up and down in a smooth curve (sine wave). The displacement is up and down, while the direction of travel is to the right. This is a classic representation of a
Transverse Wave.
*
Picture 2: The image shows a block of earth. The text says "Ground is shaking this way" with arrows pointing back and forth horizontally. The text also says "P Waves" (Primary waves), which are known to be longitudinal. The movement is parallel to the direction of travel. This is a
Longitudinal Wave.
*
Picture 3: This image shows a 3D block where the top surface is rippling up and down. The red arrow indicates the direction of travel is to the right. The movement of the ground is perpendicular to the travel. This is a
Transverse Wave.
*
Picture 4: This is another graph of a wave going up and down. Just like Picture 1, the motion is perpendicular to the direction of the wave. This is a
Transverse Wave.
*
Picture 5: This looks like an electrocardiogram (ECG) or heartbeat monitor. These graphs plot electrical activity over time. While the line goes up and down, in the context of physics worksheets comparing wave types, this visual style (a line graph with peaks and troughs) is typically used to represent
Transverse Waves.
*
Picture 6: This image shows a spring (slinky). It has labels for "Compression" (coils close together) and "Rarefaction" (coils spread apart). This back-and-forth motion is the definition of a
Longitudinal Wave.
*
Picture 7: The image is labeled "S Waves" (Secondary waves). It shows the ground moving up and down in a wavy pattern. S-waves are transverse seismic waves. This is a
Transverse Wave.
*
Picture 8: This diagram shows a grid representing a medium. It has labels for "Compressions" and "Dilations" (rarefactions). The arrows show the particles moving back and forth in the same direction the wave travels. This is a
Longitudinal Wave.
