The answer is a traveling wave
Travelling waves are temporary waves and these occur for a very short duration and move with constant speed. It is represented by an infinite rectangular waves. The crest of travelling wave move in wave propagating direction. Mathematically a periodic travelling wave is a one dimensional space that moves constantly with unvarying velocity through some medium.
Loschmidt's constant is referred to as Avogadro's number (they are the same). Their values are 6.02 times 10 to the -34 power.
