Pulsed intensity is higher because?

Pulsed intensity is higher because?

• A. It's not the whole time
• B. It's delivered for the full time
• C. It reduces energy
• D. It has a higher frequency

Answer: (A)

Pulsed delivery concentrates energy into brief on periods rather than a constant stream. Because energy is delivered only part of the time, the instantaneous (peak) intensity during those on periods can be higher than in a continuous application. The off periods mean the overall energy over the entire treatment is reduced by the duty cycle, so the average intensity stays controlled. So the reason pulsed intensity can be higher is that it’s not delivered for the whole time; energy comes in bursts, allowing higher peak output without increasing the total energy delivered. The other ideas don’t fit: delivering for the full time would be continuous rather than pulsed; simply reducing energy would lower intensity; and a higher frequency affects how often pulses occur, not necessarily the peak intensity of each pulse.
