Shadows are formed because when light hits an object, it does not pass through it. Light going around the edge of the object fills in the light void a bit, but it does not make up for the missing light.

Why the image formed on the screen of the pinhole camera is inverted?
The image formed on the screen of the pinhole camera is inverted because the aperture, which is a small hole, bends the light that enters the camera. This basically shows that light travels in straight line.
What are the conditions necessary for shadow formation?
Shadows are formed when an opaque object comes in the path of light
What can you tell from looking at a shadow?
Changes in shadow tell us where the source of light is. If you are outside, you only have one shadow because the sun is casting it. But if you have multiple shadows, then there are multiple sources of light to cast the shadows.
Are shadows made when light is blocked by an object?
No, a shadow is a concept, like cold, which is the absence of another thing (light for a 'normal' shadows or energy for shadows in general, heat for cold). As such, shadows are not made, but exist in areas absent of energy.
Property of a light that leads to formation of shadow?
They are light travels in a straight line and light cannot pass through opaque objects./ some light cannot pass through translucent objects.
Why are shadow formed?
Wait, it is not why. It's how. Shadows are formed because light travels in a straight line. Try to understand it yourself. second answer: when something come in the way of light it, light is not able to travel anymore. and the areas where is no light, it is dark and we call this dark area as shadow
Shadows are formed when light source is?
shadows are formed because the light particles (or photons as they are known scientifically) can't pass through a material, this causes them to be shown as a dark area behind the object
Why shadows are not formed at night?
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.
How are two shadows are formed?
shadows are formed when light is obstructed by an opaque body. Shadows resemble shape but not necessarily the size of the object
What is the shadows that casts suggest that light usually travels in?
Air
Is there experiments to show that light travels in straight line?
Yes shadows prove it because if light travelled in bent lines there would be no shadow.
How are shadows formed give two reasons?
shadows are formed when light is obstructed by an opaque body. Shadows resemble shape but not necessarily the size of the object
Why are two shadows of ourselves formed in the morning?
You will get two shadows if there are two light sources.
Why do you get sharp showdos?
Sharp shadows are a way of telling how fast light travels.
Why do shadows go in straight lines?
Because light travels in straight lines. (unless some form of meta-material is present in its path).
What do shadows and their shapers tell us about how light travels?
It tells us that light only travels in straight lines and cant travel through most objects.
How is the light ray theory associated with shadows?
Light ray theory and shadows. Basically the light ray theory is the theory that light always travels in straight lines, and it is linked into shadows as when an object blocks the light rays it cannot bend round the object therefore making a shadow.
