Question

Two lasers are shining on a double slit, with slit separation d. Laser 1 has a wavelength of d/20, whereas laser 2 has a wavelength of d/15. The lasers produce separate interference patterns on a screen a distance 5.60 m away from the slits.

Part A: What is the distance delta ymax-max between the first maxima (on the same side of the central maximum) of the two patterns?

Part B: What is the distance delta ymax-min between the second maximum of laser 1 and the third minimum of laser 2, on the same side of the central maximum?

Answer in m.
