Consider two identical sources of electromagnetic waves that are exactly three wavelengths apart. (Consult the notes from class for help!) Constructive interference will occur at the following angle or angles: Zero degrees Plus or minus 19.5 degrees Plus or minus 41.8 degrees Plus or minus 90.0 degrees All of the above angles
When two otherwise identical waves each with amplitude A arrive at a single point 180 degrees out of phase (one-half cycle), we observe constructive interference at this point and the combined wave has an amplitude of 2A. True False
When two otherwise identical waves each with amplitude A arrive at a single point 180-degrees out of phase (one-half cycle), we observe destructive interference at this point and the combined wave has an amplitude of zero. True False
