She proposed in 2017 that an analogous disturbance from a dark matter interaction might generate sound waves that could slightly warm the system. In a transverse wave, the motion of the particles of the medium is at right angles (i.e., transverse) to the direction the wave moves. These waves form a large shock wave. In air at atmospheric … The time taken by the periodic event to repeat itself is known as the period. Sound is a Which Word of the Day means “happening within or being the created world of a story”?

Sound wave definition: Sound waves are the waves of energy that we hear as sound. A region of increased pressure on a sound wave is called a compression (or condensation). If the prong of a tuning fork vibrates in the air, for example, the layer of air adjacent to the prong undergoes compression when the prong moves so as to squeeze the air molecules together. In a longitudinal wave, such as a sound wave, the particles oscillate along the direction of motion of the wave. The speed can be dependent on the type of medium that a wave is moving through.
