An object's shadow appears fuzzy when illuminated by a large light source because the light rays are not parallel; instead, they spread out over a larger area. This creates a gradient effect at the edges of the shadow, leading to a softer transition between light and dark. The larger the light source, the more pronounced this effect becomes, resulting in a less defined outline around the shadow.

ShadoW formed by an extended source?
A shadow formed by an extended source appears fuzzy with indistinct edges due to partial blocking of light from multiple directions. The shadow's edges may exhibit a gradient of light intensity instead of a sharp boundary seen in shadows from point sources.
Why do we have shadow?
Shadows are caused when an object is blocking the light causing the shape to appear on the ground in the opposite direction of the source of the light. A shadow only appears in the light or when any shining object faces them. All objects in the way of the light will appear with a shadow in the opposite direction of the source of the light.
What is a fog shadow?
A fog shadow is a dark area or silhouette that appears when an object blocks light from a light source and creates a shadow in foggy conditions. This occurs when the fog scatters and absorbs light, making objects appear darker when they obstruct the light source. Fog shadows are less defined and softer compared to shadows in clear conditions.
What Three things we need to have a shadow?
In order to have a shadow, you need a source of light, an object to block that light, and a surface on which the shadow is cast. When light is obstructed by an object, it creates a shadow on the surface opposite the light source.
Is translucent object casts a shadow?
Yes, translucent objects can cast a shadow. When light passes through a translucent object, it can still create a shadow behind the object depending on the intensity and direction of the light source.
What causes the fuzzy edges of shadows?
The fuzzy edges of shadows are caused by the blocking of light from a light source by an object that is not perfectly opaque. This results in a partial shadow where some light is able to pass around the edges of the object, creating a blurred or fuzzy boundary.
Why is shadow not seen in darkroom?
In a darkroom, there is no light for objects to cast shadows. Shadows are created when an object blocks light from a source, but in a darkroom environment, there is no external light source for objects to cast shadows.
Does the light of the moon cause a physical shadow?
A shadow is caused when there is less light or no light in an area. An object can block the light and thereby cause a shadow. If the light reflecting off the moon is a source of light, objects blocking this light can cause a shadow.
ShadoW formed by an extended source?
A shadow formed by an extended source appears fuzzy with indistinct edges due to partial blocking of light from multiple directions. The shadow's edges may exhibit a gradient of light intensity instead of a sharp boundary seen in shadows from point sources.
Why opaque objects do not cause a shadow?
Opaque objects do not let light to past through so it will not cause a shadow. Because light cannot get through an opaque object, it will cast a shadow on the side opposite of the light.
How does a shadow change when the light source is moved?
Depends where the light source is located and how many. Light will diffract around objects, so depending on the size of the object and the distance the light source is from it, more than one shadow can be cast, or at least it can have larger or smaller blurry edges which change when the light source is moved.
Why do we have shadow?

Why a fuzzy shadow is formed?
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 !
How can you change the shape of a shadow?
You can change the shape of a shadow by altering the position, size, or orientation of the object casting the shadow in relationship to the light source. Placing objects at different angles to the light source can also create different shadow shapes. Additionally, using multiple light sources can create complex shadow shapes.
Why is a shadow always on the opposite side of the light source?
Your shadow will fall in the direction opposite the source of light - with you between the light source and the shadow. The direction of your shadow relative to you will depend on what direction you are facing.If you are facing toward the light source, the shadow will be behind you.If you are facing away from the light source, it will be in front of you.If you have the light source to your right, the shadow will be to your left.If you have the light source to your left, the shadow will be to your right.If the light source is directly above you, the shadow will be directly under you.If you move past a light source, your shadow will move from behind you to beside you and then to in front of you.
What happens to the fuzzy region around the edge of the central region when the light source is moved away?
When the light source is moved farther away, the fuzzy region around the edge of the central region will decrease in size. This is because the light rays spread out less as they travel a greater distance, resulting in a sharper shadow edge.
Why is your shadow sometimes in front of you and sometimes. behind you?
Your shadow will fall in the direction opposite the source of light - with you between the light source and the shadow. The direction of your shadow relative to you will depend on what direction you are facing.If you are facing toward the light source, the shadow will be behind you.If you are facing away from the light source, it will be in front of you.If you have the light source to your right, the shadow will be to your left.If you have the light source to your left, the shadow will be to your right.If the light source is directly above you, the shadow will be directly under you.If you move past a light source, your shadow will move from behind you to beside you and then to in front of you.
