The source of energy for sound waves are vibrations.john vena
Tesla stated that the waves were in constant movement and there is no stationary waves.
Absorption, reflection and refraction will all change of the movement of P waves. Absorption will reduce the energy of the waves. Reflection will bounce the waves back. Refraction will change the angle of the waves based on what they are bouncing off of.
These are called s waves (secondary waves) while p waves move up and down s waves move side to side
Are they not called fissures RESPONSE TO: Are they not called fissures They are so not called fissures. Fissures are way different from what the question is. Now think, what type of movement do you feel when an earthquake happens. Of course, SHAKING.
the waves caused by an earthquake are called seismic waves
a water fall
