Question

Please Asap 

please show steps. 1. A laser with wavelength 632 nm is used to measure the diameter of a wire from its diffraction pattern. A screen is 5 meters from the wire and the linear distance from the center of the pattern to the 7th minimum is 8.35 cm. What is the diameter of the wire? 2. The largest star known is UY Scuti which has a diameter 1,700 times that of the sun and is 9,500 light years from Earth. Assuming light with a wavelength λ = 0.555 micron, what is the smallest diameter telescope mirror that can resolve the disk of UY Scuti? Show Transcribed Text
