Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Question

4. A two-point source interference pattern is generated in a ripple tank by
identical sources vibrating in phase and located 12.0 cm apart. There are 7
nodal lines observed on each side of the right bisector. If the wavelength
of the source is doubled and they remain in phase:
The number of nodal lines observed doubles
the frequency doubles
the speed of the waves doubles
the number of nodal lines decreases to half
the average distance between nodal lines decreases
