A laser beam is split into two rays by a beam splitter. The two beams are redirected through a series of mirrors and made to interfere. The interference pattern is observed on a detector. Which statement is true for the pattern made by the two laser beams?
A)
The pattern oscillates because of the phase difference of the two beams.
B)
The pattern is steady and demonstrates the phenomenon of sustained interference.
C)
The pattern is inverted, i.e. the central fringe represents destructive interference.
D)
The central fringe of the pattern is as bright as the other fringes because of the use of laser beams.
