Two shadows imply
two sources of light
and if they are in the same direction means the angle with which the source of light is striking you is different creating two different shadows.
Is it normal to have two shadows?

Most shadows made by a single light source actually do have two parts
, the . You can also get two separate shadows from one light source if you have two different objects to create them. But no, if you only have one light source and one object, you can't get more than one separate shadow.
What are 2 types of shadow?
there are two types of shadow;
a crisp edged one formed by a point source of light and a rather more fuzzy one that is formed by a larger source
. The region of deep, total shadow is called the umbra and the region of partial shadow is called the Penumbra.
Why do shadows join each other?
Point and non-point light sources
The wider the light source, the more blurred the shadow becomes.
If two penumbras overlap, the shadows appear to attract
and merge. … The umbra region does not receive any direct light from any part of the light source and is the darkest.
Why does the sun cast two shadows?
The Sun is a very large light source, its diameter exceeding that of both the Earth and the Moon. This means that,
on their journey through space
, both objects produce all 3 types of shadows.
Does a shadow have a shadow?
No.
A shadow is cast because the direct rays of light from a source are blocked by an intervening object
. The point on the floor that these rays would otherwise have hit, is consequently less brightly lit than the area around it. … If you can see the Sun, it means there can't be a shadow.
What do shadows symbolize?
Shadows symbolize
suspense, uncertainty, and dark magic
. But they can also be positive. They can represent relief and protection. But the most overwhelming shadow symbolism is that of secrecy and the unknown.
What are the three types of shadows?

are three distinct parts of a shadow, created by any light source after impinging on an opaque object.
What causes shadow on moon?
When the sun, the Earth and the moon are aligned in space (nearly or perfectly), with the Earth between the sun and moon, then Earth's shadow falls on the moon's face. … During a
lunar eclipse
, a very small amount of light from the sun filters through Earth's atmosphere onto Earth's shadow on the moon.
Which part of the shadow falls on the moon?
The inner part of the shadow, called
the umbra
, is the darkest part. If you were to stand on the Moon under the umbra, your view of the Sun would be completely blocked. Under the outer part, the penumbra, the Sun is only partially blocked. This is why the Moon is more darkened under the umbra than under the penumbra.
Why do shadows kiss?
Why does this happen? This is because
the sun is an “extended” light source
, as opposed to a point light source. Because of this, there is an area called the penumbra, where the shadowing object creates a partial shadow. When two penumbras meet, it makes the “kissing” darker shadow.
How are shadows useful?
Humans constantly, but unconsciously, use shadows
to judge the shape of objects in their environment
. Because shadows reveal much about an object's extension in space, they are often used to heighten the illusion of depth in a painting.
What is Penumbra Umbra?
(i) Umbra means ”
shadow
” while ”penumbra” means to hang on the shadow or almost a shadow. … When a partial lunar eclipse occurs, the umbra merely covers a part of the moon. The outer shadow of the earth falls on the moon during a penumbral lunar eclipse.
Can moonlight cast a shadow?
