Two lasers are shining on a double slit, with slit separation ddd. Laser 1 has a wavelength of d/20d/20, whereas laser 2 has a wavelength of d/15d/15. The lasers produce separate interference patterns on a screen a distance 5.30 mm away from the slits. Part A
Which laser has its first maximum closer to the central maximum?
Part B
What is the distance \Delta _y__max-max_ between the first maxima (on the same side of the central maximum) of the two patterns?
Express your answer in meters.
Part CWhat is the distance \Delta _y__max-max_ between the second maximum of laser 1 and the third minimum of laser 2, on the same side of the central maximum?
Express your answer in meters.
