The emission of the light waves in the lasers allows them to overlap properly to create larger waves, which means that _____ overlap.

A. the waves do not
B. the troughs of one wave and the crests of another
C. identical parts of the two waves
D.
only fifty percent of one wave and another wave

Respuesta :

The emission of the light waves ..................... which means that THE TROUGHS OF ONE WAVE AND THE CREST OF ANOTHER overlap.
When the trough and the crest of wave overlap, it results in constructive interference and the amplitude of the two waves are added together  to form a larger amplitude.
