How shadows are formed?
A shadow is formed when an opaque object blocks the travel of light on a second object. Light travels in straight lines and any barrier along its path averts the rays striking the barrier.This forms a region of darkness, shaped like the surface of the object obstructing the light. A shadow takes up all the space behind the object with light before it. Its cross-section is a two-dimensional outline of the obstructing object. The shadow is smaller if the angle between an object and the path of light is nearer to 90°. It is longer if the angle between the surface and the path of light is smaller. If the obstructing object is closer to the starting point of light, the shadow is larger.
What causes a shadow to form?
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 screenPlaces to do:- A dark roomHow 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.
Why a gray halo surround a dark shadow made by a light bulb and an object?
because the light bulb made the gray halo have a shadow
Why a fuzzy shadow is formed?
The size of shadow an object casts, is directly related to the position of a light source. the higher up a light source is in relation to the object, the shorter the shadow will be. Shadows cast by objects lit by the sun in the morning or evening are long, because the sun is low in the sky. At mid-day, the shadow is shorter because the sun is higher. Try it yourself with a torch - and see !
When you heat an object up what happens to the atomsmolecules that it is made of?

What is dark which is made by light?
I don't know if I have misunderstood this question, but dark is the absence of light. The only darkness that I can think of which is made by light are shadows, when light rays are blocked by an opaque object.
Can you say that shadow is the consequence of rectilinear propagation of light?
Yes, shadows are formed when an object blocks the path of light, resulting in a region of reduced illumination behind the object. This is due to rectilinear propagation of light, where light travels in straight lines until it is blocked or redirected by an object, creating shadows.
What is made of light but it is dark?
A shadow is made of light, as it is created when light is blocked by an object, causing darkness where the light cannot reach.
How are shadows made?
Shadows are made when an object blocks light from a source, creating a darker area behind the object. Light travels in straight lines, and when an object interrupts the path of light, a shadow is formed on the surface where the light cannot reach. The position and size of the shadow depend on the angle and intensity of the light source in relation to the object.
How do shadows get made?
It occupies all of the space behind an opaque object with light in front of it.
Are there shadows made by the sun even at night?
Yes, when it's night here, the sun is shining and making shadows on the other side of the world.
What are shadows made out of?
shadows are made of a dark matter called eucloid which emerges out of the object only in darkness
What is the difference between a silhouette and a shadow?
A silhouette is named after Etienne de Silhouette who loved hand-cut silhouettes for their frugal quality. A good silhouette is not made from a shadow, it is hand-cut by a real artist. Shadows come from blocked light reflectd off an object. In Jung, the shadow is the dark side of a person.
What dark area made by an object blocks out light?
A shadow is a dark area created when an object blocks light from reaching a surface. Shadows are formed when an object obstructs the path of light, causing a shadow to appear on the opposite side of the light source.
What fact about the way light travels explains why shadows are made?
Light travels in straight lines. When an object obstructs the path of light, a shadow is created because the light cannot pass through the object. The shadow is formed on the side opposite to the direction of the light source.
What is a shadow and what is it formed of?
In short, nothing. A shadow is a dark area within a brighter area. It doesn´t have any substance as it is just a place where light is not falling as its being blocked by somthing. A shadow can be thought of as an opposite to a rainbow which is made by light shining on a specific place. Both have no substance but seem to be solid and can appear to move.
Who discovered shadows?
No single person can be credited with the discovery of shadows, as they have always existed as a natural phenomenon when an object blocks light. However, ancient civilizations like the Greeks and Egyptians studied and made observations about shadows, contributing to our understanding of them.
