A student creates a two-point source interference pattern in a ripple tank with two sources operating in phase. A point on the eighth nodal line is 1.25 m from the centre of the two sources and 48.0 cm from the perpendicular bisector of the two sources. If the source separation is 2.75 cm, find the wavelength of the waves. A student creates a two-point source interference pattern in a ripple tank with two sources operating in phase.
