An object (Materials) that does not allows anylight to pass through will form a shaddow:

Eg.

- Opaque ( Can't let any light to pass through)

- Translucent (Allows a little bit of light to pass through)

If you want to make sure Im correct do this experiment:

Instruments:

- A Cloth ( Opaque)

- A torch

- A Tracing paper ( Translucent)

- A screen

Places to do:

- A dark room

How to do? :

- Use your torch and shone on the cloth facing on the screen, what will you see?

- Use your torch and shone on the tracing paper on the screen, what will you see?

You will see an unclear shadow and a clear shdow on the screen! You may also add one more item a Transparent object! You will see I'm quite correct...
Shadows are formed by light, because if light shines onto an object, and the object blocks the light, the light will go sideways of the object, and therefore, a shadow is formed.
Light can only travel in straight lines. If light is coming from one main source, then an object that does not allow light to pass through it, will have an absence of light behind it, i.e.a shadow.

To keep it simple:

When light strikes an object, some light reflects (based on the colour of the object). when there is an obstacle in the way of the light, and it cannot pass, there is no light to reflect, and thus a shadow is formed.

A SHADOW IS FORMED WHEN LIGHT SHINE AT AN OPAQUE OBJECT BLOCKING THE LIGHT RAY CAUSING A SHADOW BECAUSE LIGHT ONLY GOES IN A STRAIGHT LINES.

Shadows are created when something gets in the line of light and blocks the light from shining and creates the darkness known as shadows.

What causes shadows to appear?

First of all, let's get one thing straight, everybody has a shadow, right,? And your question is "What causes shadows to appear?". Well, if it's sunny outside, the you have a shadow and when it's cloudy, your shadow is less visible. So shadows have something to do with the sun. When the sun hits an object is causes the object to have a dark side, away from the sun. So, the sun causes shadows to appear.well the topic is MOUSTACHE shadow and Actually NO that cant be it ,the shadow remains when youre in a dark room

How can a shadow be reflected?

It is actually impossible to reflect a shadow, as a shadow is merely an absence of light. However, what IS reflected is the light surrounding the shadow. When this light is reflected, it forms a reflected image of the light's shape, complete with a lack of light, or shadow. In this way, it can look like a shadow is reflected.


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.

Shadows can only form when there is light present. A shadow is the result of a solid object blocking visible light. As a mirror is a solid object it can indeed produce a shadow, but nothing can form a shadow in the dark, there must first exist a light source.
