CEM 141 PASSED Exam Questions and 
CORRECT Answers

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...
