Laser light of wavelength 601 nm is incident on a circular aperture which has a diameter of 0.025 mm.
A diffraction pattern is observed on a screen which is placed 61 cm from the aperture.
Give your answer to at least three significant figures. Answer must be accurate to 1%.
What is the diffraction angle, θ, of the first diffraction minimum? (degrees)
What is the distance, on the screen, from the center of the central bright spot to the first dark ring? (cm)
