Here are the essential concepts you must grasp in order to answer the question correctly.
Interference of Light
Interference occurs when two or more light waves overlap, resulting in a new wave pattern. In the context of a double-slit experiment, constructive interference produces bright bands (maxima) where the waves are in phase, while destructive interference leads to dark bands (minima) where the waves are out of phase. Understanding this principle is crucial for analyzing the resulting pattern from the slits.

Young's Double-Slit Experiment
Young's double-slit experiment demonstrates the wave nature of light through the creation of an interference pattern. The distance between the slits and the screen, along with the wavelength of the light, determines the spacing of the bright and dark bands. The formula for the position of these bands is essential for calculating slit width and separation.

Wavelength and Slit Separation
The wavelength of light is a critical factor in determining the interference pattern produced by the slits. The separation between the slits affects the angle at which light waves interfere, influencing the distance between bright bands on the screen. By applying the relationship between wavelength, slit separation, and the observed pattern, one can derive the necessary dimensions of the slits.
