PHYS 1260 Exam 4 with Verified Answers 100% Pass 1. Superposition and Interference 2. Superposition and Interference part 2 - same wave + same wave = reinforcement - two opposite waves = cancellation - two similar waves = partial cancellation - interference patterns of overlapping waves from 2 vibrat- ing 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 ...

CEM 141 PASSED Exam Questions and CORRECT Answers Evidence that light is a wave - Ans Light is a wave because when light goes through 2 slits a diffraction pattern occurs. Reasoning that light is a wave - Ans the waves from each slit meet "in phase" or "out of phase" when the waves meet in phase constructive interference occurs and the wave intensity increases. this is seen by bright spots in the patterns. when the waves meet out of phase destructive interference occurs and the w...
