Two lasers are shining on a double slit, with slit separation . Laser 1 has a wavelength of , whereas laser 2 has a wavelength of . The lasers produce separate interference patterns on a screen a distance 5.80 away from the slits.(adsbygoogle = window.adsbygoogle || []).push({});

Part A

Which laser has its first maximum closer to the central maximum?

Part B

What is the distance between the first maxima (on the same side of the central maximum) of the two patterns?

Express your answer in meters.

Part C

What is the distance 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.

Not sure where to start .......

currently working with wavelength = (Y*D)/(mR)
