A laser beam is aimed through a circular aperture of diameter 1 mm. a. If the laser beam is red with a wavelength of 632.8 nm, what is the angle from the center of the Airy disk to the first dark ring? (2 points)

sin(p) = 632.8*10^-9 / .001

sin^-1(.0006328) = .0363 degrees

b. If the screen you are projecting the Airy disk onto is 2 m from the aperture, what is the distance between the center of the disk and the first dark ring? (2 points)

Thanks everyone who can help!
