Waves that are emitted in phase from two sources will undergo constructive interference when the paths from the sources differ by
A)an odd half-integer number of wavelengths.
B)a whole integer number of wavelengths.
C)an odd one-third-integer number of wavelengths.
D)any quarter-integer number of wavelengths.
E)none of the above.

Question

Quizplus · Accepted Answer
