Solve the following problem given below:
Problem: Parallel rays of monochromatic light with wavelength 594nm illuminate two identical slits and produce an interference pattern on a screen that is 75.0cm from the slits. The centers of the slits are 0.640 mm apart and the width of each slit is 0.434 mm.
A- If the intensity at the center of the central maximum is 3.80 × 104 W/m2, what is the intensity at a point on the screen that is 0.730mm from the center of the central maximum?
I need help to solve the above problem and please show all work thank you!
