PHYS 1260 Exam 4 with correctly explained test. Superposition and Interference - correct answers.- same wave + same wave = reinforcement - two opposite waves = cancellation - two similar waves = partial cancellation - interference patterns of overlapping waves from 2 vibrating sources - interference pattern = caused by interference b/w a pair of waves - constructive interference produces bright region where waves reinforce each other (waves arriving in phase) - destructiv...

Scatter radiation - ANSWER-- form of secondary radiation - result of xray photon deflected in all directions travelling to all parts of client's body and to all areas of the op - detrimental to client and radiographer Compton scatter - ANSWER-- Evidence of ionization - xra photon collides w outer shell + gives up part of its energy to eject electron from it's orbit - ejected electron is known as compton or recoil electron Coherent scatter - ANSWER-- unmodified scatter - when low ene...
