Compute each part of given problem:

Problem: Light of wavelength 472 nm falls perpendicularly on a pair of slits. Each slit is 0.00889 cm wide. The centers of the slits are separated from each other by 2.49×104 m. A screen is placed very far from the slits.

Part I: What is the angular position of the first diffraction minimum, if one of the slits is covered?

Part II: If the slits are both uncovered, what are the angular positions of the first three interference maxima that lie to the right of the central maximum?

Part III: How many of the three interference maxima that you found in part a lie within the central diffraction maximum?

I just want the right answer; give all answers as positive values, thank you.
