How many milliseconds between blasts defined as separate blasts?

• A. 8 milliseconds
• B. 2 milliseconds
• C. 50 milliseconds
• D. 100 milliseconds

Answer: (A)

Eight milliseconds is the standard minimum interval that defines separate blasts. The idea is to give the energy from the first blast time to dissipate so the next detonation can be counted as a distinct event, reducing overlap of shock waves and ensuring clear timing and safety checks. If the interval were too short, the second blast could ride on the tail of the first, making them appear as a single event. While longer intervals like fifty or one hundred milliseconds would definitely create clearly separated blasts, the definition of separate blasts uses the smallest reliable gap, which is eight milliseconds.
