Quizplus · Accepted Answer

As the focal spot size decreases, the size of the umbra also decreases, resulting in improved image quality. This happens because a smaller focal spot can produce more precise and sharp images. Additionally, the penumbra decreases, which means there is less blurring around the edges of the image. This also contributes to an improvement in image resolution, making smaller details more discernible. Therefore, all of the above statements are correct.
