A double-slit interference pattern is produced on a screen using monochromatic light of wavelength 560 nm. We first marked the location of the m=2 destructive order minimum on the screen with the letter "X". When we use the light source with a new wavelength, the m=3 constructive order maximum now appears at the location of the "X" on the screen. What is the wavelength of the new light source? (Give your answer in units of nanometers and round it to the closest integer value.)
