What are Sneaker Waves? Sneaker waves are unusually large ocean waves that appear suddenly and without warning. Small children should be watched around the ocean to protect them from the sudden dangers associated with sneaker waves.
Shock wave. In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance. When a wave moves faster than the local speed of sound in a fluid, it is a shock wave. Like an ordinary wave, a shock wave carries energy and can propagate through a medium; however, it is characterized by an abrupt, nearly discontinuous change in pressure, temperature and density of the medium.
