Which term specifies the duration of a single electromagnetic pulse?

• A. PULSE DURATION
• B. PULSE LENGTH
• C. PULSE WIDTH
• D. PULSE PERIOD

Answer: (C)

The duration of a single electromagnetic pulse is described by its pulse width. It is the time interval during which the pulse is present above a chosen amplitude threshold (often defined as the full width at half maximum). This distinguishes it from the pulse period, which is the time between the starts of successive pulses. The term pulse length can refer to the spatial extent the pulse travels during its duration, not the time duration itself. While some sources may use pulse duration interchangeably with pulse width, pulse width is the standard term for the temporal length of a single pulse.
