Question

How does the intensity change on both sides of \[\theta=0\]?

पर्याय

• It remains maximum at every secondary maximum

• It is maximum at the centre and falls off on both sides

• It falls off on only one side of the centre

• It is minimum at the centre and rises on both sides

Answer 1

The intensity is greatest at the centre, where \[\theta=0\]. It falls off on both sides, although weaker secondary maxima occur between the minima.
