The Mach number is one of the vital boundaries of collisionless shocks. Understanding shock material science requires information on the spatial scales in the shock change layer. The standard techniques for deciding the Mach number and the spatial scales require concurrent estimations of the attractive field and the molecule thickness, speed, and temperature. While attractive field estimations are ordinarily of top caliber and goal, molecule estimations are frequently either inaccessible or not appropriately acclimated to the plasma conditions. We show that hypothetical contentions can be utilized to beat the constraints of perceptions and decide the Mach number and spatial sizes of the low-Mach number shock when just attractive field information are free.
