Academics

A slit 0.240mm wide is illuminated by parallel light rays with a wavelength 540nm . The diffraction pattern is observed on a screen that is 2.50m from the slit. The intensity at the center of the central maximum (? = 0?) is 6.70×10?6W/m2 .

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

What is the intensity at a point on the screen midway between the center of the central maximum and the first minimum?
