SPI EXAM STUDY GUIDE (EDELMAN) CHAPTER 5 INTENSITIES EXAM QUESTIONS AND ANSWERS 100% CORRECT!!

Peak Intensity - ANSWER Maximum value Average Intensity - ANSWER The mathematical middle value Temporal Intensity - ANSWER Refers to all time, transmit, and receive. (US beam doesn't have same intensity at different times) Pulsed Intensity - ANSWER Refers to only transmit time. (Average intensity for pulse duration only) Spatial Peak Intensity (Isp) - ANSWER Beams intensity at the location where it is maximum. Spatial Average Intensity (Isa) - ANSWER Average intensity across the entire beams cross sectional area. Temporal Peak Intensity (Itp) - ANSWER Measuring the intensity of the beam at the instant in time of its maximum value. Imax (Im) - ANSWER The average intensity during the most intense half cycle. Pulse Average Intensity (Ipa) - ANSWER Taking the average intensity during the pulse duration (the transmit time) Temporal Average Intensity (Ita) - ANSWER Averaging the intensity during the entire PRP (both transmit and receive time) Rank the temporal intensities from largest to smallest - ANSWER Itp, Imax, Ipa, Ita Isptp - ANSWER Measured at the location where intensity is maximum and at the instant in time when the most powerful part of the pulses passes.
