A Rayleigh wave is a seismic surface wave causing the ground to shake in an elliptical motion(they move in a surafce rolling manner). A seismic wave means a earthquake wave, so Rayleigh wave is realted to the motion of earth and its crust. Rayleigh waves are formed when the particle vibrate with the combination of both transverse and longitudinal waves. This vibration gives rise to a wave which moves elliptically backwards that is Rayleigh Wave. Rayleigh waves are really fast they move with the spped 10 times faster than the speed of light. Rayleigh waves are generated by the interaction of P or compressional and S or shear waves(P ans S Waves are inside the Earths Crust) at the surface of the earth.

Love waves or Q waves or Quer Waves are surface seismic waves that cause horizontal shifting of the Earth during an earthquake. A Love wave is a surface wave having a horizontal motion only. Love waves are formed when the earth particles move in a transverse wave manner creating a wave travelling perpendicular to the direction the wave.

The muscles are composed inside mainly of fibers, filaments and proteins, where it is important to consider the <u>length-tension</u> relationship of the thick and thin filaments to know the tension.
<h3>What is muscle contraction?</h3>
It is an organized and natural event that takes place at the level of the muscles when the fibers and proteins inside them come together, and tension is produced in the area.
<h3>Characteristics of muscle contraction</h3>
- In a muscle contraction, a tension is generated that depends on the length-tension relationship, which causes a displacement of the muscle filaments.
- The proteins actin and myosin join together, and a force is generated so that the final movement is achieved.
- To know the tension, the muscle changes length and measurable external work is produced from the force and distance traveled.
Therefore, we can conclude that the contraction allows us to make movements to reach and carry our extremities to different places.
