The width of the light source is the main cause of the shadow edge becoming more blurred as the mask approaches the light source.
But light refraction around the edge of the mask may also be a minor component.
if an object is moved closer to the light source, the shadow gets bigger,if it goes further away,the shadow gets smaller
If you are using a point light source, the shadow's size is the object's size divided by the distance from the light source to the object multiplied by the distance from the light source to the shadow.
When object is closer to source of light ,the shadow formed of the object is shorter and darker.
The shadow will get longer.
cooler than the lgith source
More well defined in outline, sharper in image.
To make shadows sharper, you can increase the light source’s intensity, focus the light on a smaller area, or decrease the distance between the object and the surface where the shadow is cast. Using a direct, strong light source positioned closer to the object will also help create sharper shadows.
The further the light source is from the object, the smaller the shadow formed and vice versa.
I understand that the closer the object to the light source the sharper the shadow and visa versa or depending on the intensity of the light source the more intense the light the sharper the shadow. However I have recently had a shadow problem that has made me question this. I have tried 3 different materials of almost equal dimensions and found that out of the 3 materials (cardboard, wood, aluminum) I found that aluminum produces a significantly sharper shadow. I can not explain this.......
The size of shadow an object casts, is directly related to the position of a light source. the higher up a light source is in relation to the object, the shorter the shadow will be. Shadows cast by objects lit by the sun in the morning or evening are long, because the sun is low in the sky. At mid-day, the shadow is shorter because the sun is higher. Try it yourself with a torch - and see !

You can either move closer to the light source or move the light source closer to you. The size of your shadow just depends upon how much of the light you are obscuring so the more you block out, the bigger your shadow.
If you are using a point light source, the shadow's size is the object's size divided by the distance from the light source to the object multiplied by the distance from the light source to the shadow.
The size of a shadow has everything to do with placement of the light source, the object, and the background on which the shadow is cast. In general, if the light source is close to the object and the background is further away then the shadow is larger than the object. The opposite is true if the light source is further away. Another part of the equation has to do with angles. This is what we commonly observe happining to shadows at different times of the day; long shadows in the morning and evening and smaller shadows around the middle of the day.
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.
