### 7-Types of Mechanical Waves.pptx

• 2. Types of Mechanical Waves
• 4. Mechanical waves can be classified according to how the motion of individual particles of the medium is related to the motion of the wave itself.
• 7. In the case of waves in a string, the particles oscillate up and down while the wave moves horizontally.
• 8. Transverse Wave
• 9. The direction of motion of the particles of the medium (string) is perpendicular to the direction of motion of waves. These waves are called transverse waves.
• 10. Transverse Wave Direction of particle motion Direction of energy transfer
• 13. In the case of waves in a spring being pushed or pulled, a series of compressions (areas where coils are close together) and expansions (rarefactions) occur.
• 15. The particles of a spring move back and forth horizontally and are in the same direction as the line of propagation.
• 16. Longitudinal Wave
• 17. Longitudinal Wave
• 18. These waves are called longitudinal or compressional waves.
• 23. Surface waves have both transverse and longitudinal properties.
• 24. Surface Wave
• 26. These waves make the particles in the medium move both horizontally and vertically as the wave moves across the surface.
• 30. 1. The particles in this wave oscillate up and down while the wave moves horizontally. 2. The particles in this wave move the same as the direction of the wave. 3. This wave has the properties of longitudinal and transverse wave. 4. This re the waves that travels in string. 5. One example of this wave is the sound wave. 6. This wave only occurs in the surface. 7. This wave happens in the springs.
