Airplanes have now shadow because the airplane is too far above the ground which means that the light ray that is coming from sideways illuminates the shadow that is supposed to be cast on the ground.

However if you see an airplane on the ground you can see the shadow of the airplane.

Not all objects form a shadow as only opaque and translucent objects create shadows.

Shadows are real as they occur with the blockage of light of an opaque object.

Shadows do move with us because a shadow is formed when the opaque object blocks the path of light.

So because we are opaque objects the shadow moves along with us as we block the path of light.

Shadows are faster than light.

Shadows do not have matter nor do shadows have energy.

Shadows do not have energy as a shadow is a lack of light and so a shadow has no mass which means a shadow is not an objector nor is it energy.

Shadows also can go faster than light in some cases because they are not objects.

Things that cannot form a shadow are transparent objects as shadows are only formed in translucent and opaque objects.

For example glass cannot form a shadow because light passes through it.

A shadow is black due to the absorption or the absence of light.

When the shadow is formed it occurs due to the absorption of all light by the object from a light emitting source.

All shadows are not black or dark.

When the lights of different colors shine on the same spot of a white surface the light that is reflecting from that spot to the eyes is called an additive mixture because it's the sum of all light.

When a shadow is formed it happens due to absorption of all light by an object from a light emitting source.

As a result, a shadow is produced which is due to absorption or absence of light, hence black in color.

The type of shadow that is the darkest are shadows formed by translucent objects.

The 3 properties of a shadow are they are always dark in color, they are formed opposite to the source of light and they are formed when an opaque object comes between the source of light and the screen.

The 3 conditions of a shadow are a screen, there should be a light source and there should be an opaque object.

Shadows do not need light to form although most shadows are formed by light going past the edges of the material which make the outline for the shadow.

Shadows work by way of the light rays going past the edges of the material or opaque object.

The rays of light do not pass through the object but instead go past the edges of the material.

Rays of light are what creates shadows.

When an opaque object or material is placed in the path of rays of light a shadow is formed.

The opaque material however does not let the light pass through it and instead the lights rays that go past the edges of the object or material make an outline for the shadow.

The three things that are needed to form or create a shadow are.

A source of light.
An opaque object whose shadow has to be formed.
A screen on which shadow is to be formed.

When light reaches an opaque (solid) object, the light is prevented from moving through the object, leaving an area of darkness on the other side (a shadow).

If an object is transparent, the light can move through it.

If the object is shiny, the light will be reflected off of it into a different direction.

Transparent objects cannot form a shadow.

Shadows are only formed in opaque or translucent objects.

If you take a glass slab, no shadow is formed because it allows light to pass through it.

A shadow is a dark area where light from a light source is blocked by an object.

It occupies all of the three-dimensional volume behind an object with light in front of it.

The cross section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.
