# Two-point source interference pattern

## Homework Statement

A two-point source interference pattern is generated by sources operating in phase at 1.0 Hz. The sources are 2.0 m apart and the wavelength of the waves is 0.60 m. At what angles, measured from the centre line of the pattern, are the nodal lines produced located?

They want to sub in for various values of n? or am i missing something it seems to simple? i am using sintheta=(n-0.5)($$\lambda$$/d)
