The shockwave from the Chelyabinsk meteor that rocketed across the Russian morning sky on 15 February 2013. In physics, a shock wave (also spelled shockwave ), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through.
