What is your idea :

Inverse square law (ISL) I1/ I2 =(d2)2/ (d1)1 As I = intensity of the beam and two main factor that affecting the quality and intensity of beam are KVp & mas therefore, Kvp1 * mas1 /kvp2 *mas2 =(d2)2/ (d1)1 As kvp is instant, it cross of equation mas1 /mas2 =(d2)2/ (d1)1 direct square law (DSL)

 It could be applying on KV according to %15 rule, (MA) or(S) individually

Are they the same mathematically or not ?
