The size of the shadows formed changes if the distance between the object and the screen is also changed. If there is an increase in the distance between the screen and the object, the size of the shadow also increases.
In the interference diffraction phenomenon, the relationship between the ratio of the distance between two slits and the screen (d) to the wavelength of light () determines the pattern of interference fringes observed on the screen. This relationship affects the spacing and intensity of the fringes, with smaller ratios leading to wider spacing and more distinct fringes.
If the object distance is decreased in a pin hole camera, the image size will increase. If the object is too close, the full image will not be formed and the screen will appear dark.

When a opaque object is placed between the source of light and the screen light from the source falls on a screen aceept some part which looks the shape of the object the Part of the screen wre high does not fall due to the object is called a shadow
A converging lens produces a real image on a screen when the object is placed beyond the lens's focal point. The image is inverted and can be larger or smaller, depending on the distance between the object and the lens.
More information, or an image, is required to answer this question.
Another term for Fraunhofer diffraction is far-field diffraction. This type of diffraction occurs when the distance between the diffracting object and the screen observing the diffraction pattern is much greater than the dimensions of the diffracting object.

FRESENEL DIFFRACTIO1) Both the incident and diffracted wavefronts are spherical or cylindrical.2) the source must be close to he obstacle.FRAUNHOFFER DIFFRACTION1) Both the incident and diffracted wavefronts are plane wavefonts.2) the source must be infinite distance from the obstacle.

An object seen through a concave lens will appear smaller, upright, and virtual - meaning it will not project a real image on a screen. The image will be on the same side as the object and its characteristics will depend on the distance of the object from the lens.
