For the formation of a shadow on a screen, three essential elements are required: a light source, an opaque object, and a surface (the screen) for the shadow to appear on. The opaque object blocks the light from the source, preventing it from reaching the screen in certain areas. This results in a dark shape or shadow that corresponds to the outline of the object on the illuminated surface. The position and angle of the light source, as well as the distance between the object and the screen, also influence the size and clarity of the shadow.

What are the essential condition for shadow formation?
Three essential conditions for shadow formation are a source of light, an object to block the light, and a surface to project the shadow onto. When light is blocked by an object, it creates an area behind the object where light cannot reach, resulting in a shadow being cast on the surface opposite the light source.

Why the shadow of a flying bird not seen in the earth?
The shadow of a flying bird may not be seen on the ground because the bird is often higher in the sky than the angle at which the sun's rays hit the ground, resulting in the shadow being cast above where we can see it from the ground. Additionally, the bird's movement and the speed of the sun may also contribute to the shadow not being visible to us.

When object is moved closer to screen what happens to the shadow?
Well, darling, when you move an object closer to the screen, the shadow it casts will appear larger and more defined. This happens because the object is blocking more light from reaching the screen, creating a more prominent shadow. So, in simple terms, bring that object closer and watch that shadow grow!
When a shadow is formed on a screen what would happen to the shadow if the screen were moved further away from the bulb?
The shadow would become larger and less defined as the screen is moved further away from the bulb. This is because the light rays from the bulb spread out further apart as the distance increases, resulting in a larger, more diffuse shadow.
Shadow formation is based on which principle?
rectiliner propagation

Answer
What is Shadow Formation?
That light cannot pass through some materials, and that this leads to the formation of shadows.
What happens to the shadow if you move the puppet close to the screen?
If you move the puppet closer to the screen, the shadow will appear larger and more defined on the screen due to the closer proximity between the light source (screen) and the puppet. The shadow will also appear more focused and detailed since the light rays are more concentrated and less diffused.
What factors affect the size of a shadow formed on a screen?
The size of the shadows formed changes if the distance between the object and the screen is also changed. If there is an increase in the distance between the screen and the object, the size of the shadow also increases.
