Step 1
Unsharp masking is a technique used in image processing to enhance the sharpness of an image. It works by creating a blurred version of the original image, subtracting this blurred version from the original image, and then adding the resulting "mask" back to the Show more…

A beam of light passes through a single slit to create a diffraction pattern. How will the spacing of the bands in the pattern change if the width of the slit is increased? The width of the spaces between the bands will remain the same. The width of the spaces between the bands will increase. The width of the spaces between the bands will decrease. The width of the spaces between the bands will first decrease and then increase.
