A slit 0.350 mm wide is illuminated by parallel rays of light that have a wavelength of 600 nm . The diffraction pattern is observed on a screen that is 1.30 m from the slit. The intensity at the center of the central maximum (θ=0∘) is I0.

A

What is the distance on the screen from the center of the central maximum to the first minimum? in mm

B

What is the distance on the screen from the center of the central maximum to the point where the intensity has fallen to I02? ((Hint: Your equation for β cannot be solved analytically. You must use trial and error or solve it graphically.) in mm
