A beam of monochromatic light illuminates a slit of width w and forms a diffraction pattern on a screen located a distance D ≫ w from the slit. For which color of incident light is the width of the central band greater? blue yellow both are equal

The yellow color of incident light is the width of the central band greater.

The following things should be considered:

Therefore we can conclude that the yellow color of incident light is the width of the central band greater.

Yellow

Explanation:

Yellow light has lesser energy than blue light, this means blue light has a much smaller wavelenght. For the width of the central band to be greater, the wavelenght has to be more, and yellow light has a much larger wavelenght

i think the answer is a, hope this : )

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
