EDELMAN SPI EXAM CH. 5 INTENSITIES QUESTIONS
WITH VERIFIED ACCURATE ANSWERS
What are the 5 intensities ? - Answers -Spatial, Peak, Average, Temporal, Pulsed
Spatial Intensity - Answers -Refers to distance, location, or space. (US beam doesn't
have same intensity at different locations)
Peak Intensity - Answers -Maximum value
Average Intensity - Answers -The mathematical middle value
Temporal Intensity - Answers -Refers to all time, transmit, and receive. (US beam
doesn't have same intensity at different times)
Pulsed Intensity - Answers -Refers to only transmit time. (Average intensity for pulse
duration only)
Spatial Peak Intensity (Isp) - Answers -Beams intensity at the location where it is
maximum.
Spatial Average Intensity (Isa) - Answers -Average intensity across the entire beams
cross sectional area.
Temporal Peak Intensity (Itp) - Answers -Measuring the intensity of the beam at the
instant in time of its maximum value.
Imax (Im) - Answers -The average intensity during the most intense half cycle.
Pulse Average Intensity (Ipa) - Answers -Taking the average intensity during the pulse
duration (the transmit time)
Temporal Average Intensity (Ita) - Answers -Averaging the intensity during the entire
PRP (both transmit and receive time)
Rank the temporal intensities from largest to smallest - Answers -Itp, Imax, Ipa, Ita
Isptp - Answers -Measured at the location where intensity is maximum and at the
instant in time when the most powerful part of the pulses passes.
Isppa - Answers -Measured at the location where intensity is maximum averaged of the
transmit time.
