A slit 0.390 mm wide is illuminated by parallel rays of light that have a wavelength of 580 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. What is the distance on the screen from the center of the central maximum to the first minimum? y1=? mm 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.) y=?mm

A slit 0.390 mm wide is illuminated by parallel rays of light that have a wavelength of 580 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.

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

y1=? mm
