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 4.90m away from the slits.

1. What is the distance Δy_max-max between the first maxima (on the same side of the central maximum) of the two patterns?

2. What is the distance Δy_max-min between the second maximum of laser 1 and the third minimum of laser 2, on the same side of the central maximum?
