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.......
Shadows are caused by something BLOCKING the light. You can have shadows in space, if something is blocking the light. On Earth, shadows often look fuzzy; this is caused by the Sun's light being scattered in the air. In space, there is nothing to scatter the light, so shadows are sharp-edged and clear.
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.
Sharp shadows are a way of telling how fast light travels.
Transparent materials do not form shadows. Translucent materials form fuzzy shadows. Opaque materials form well-defined shadows.

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.
Sound waves do not produce sharp shadows due to their ability to diffract around obstacles, resulting in a gradual decrease in intensity rather than a distinct shadow. Water waves can produce sharp shadows in certain conditions, such as when the obstacle is large relative to the wavelength of the waves, leading to a clear blockage of the wave energy.
SHADOWS
Shadows give us information about shapes of objects. Sometimes, shadows can also mislead us about the shape of the object. :)
it is because a shadow is a blocking of a light source and at night there are not many light sources activated. But there are shadows from Moonlight sometimes. And sometimes in your household.
sometimes it depends on the light.
If they are tan and hard they are most likely dead. Sometimes they might be slightly alive if they are fuzzy and have some color.
