It's hard to explain this in words but here goes.
There are two ways a shadow changes size based on the position of the light source.
- If the light is just above and in front of the object the shadow is long, but as the light moves above the object the shadow gets shorter and shorter and shorter until when the light is directly above the object there is little to no shadow at all.
- If the light is directly in front of an object, like a person, as the light gets closer the light rays can only get past the object at a wider and wider angle (out to the sides) so the area with no light (the shadow) becomes wider and wider.

What things might affect the size and position of a shadow?
The size of a shadow is affected by the angle and intensity of the light source, the distance between the object and the light source, and the size and shape of the object. The position of a shadow is influenced by the relative positions of the light source, the object, and the surface on which the shadow falls.

Is the shadow longer behind an object?
Yes, the shadow is longer behind an object, as it is cast by the object blocking the light source. The length of the shadow will depend on the angle and position of the light source in relation to the object.
What direction does the shadow point at night under a street light?
The shadow of an object under a street light will point away from the light source, opposite to where the light is coming from. This is because the light source casts the object's shadow in the direction opposite to its position.
What are essential for the formation of shadow on the screen?
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.

The position of a shadow is influenced by the relative positions of the light source, the object, and the surface on which the shadow falls.

What three things do length and position of a shadow changing depend on?
The length and position of a shadow depend on the angle of the light source, the distance between the object and the surface the shadow falls on, and the height of the object casting the shadow.
What direction does a shadow move?
A shadow moves in the opposite direction of the light source that is causing it. As the position of the light changes, the shadow will shift accordingly.
Is the shadow longer behind an object?
Yes, the shadow is longer behind an object, as it is cast by the object blocking the light source. The length of the shadow will depend on the angle and position of the light source in relation to the object.
What 3 things do you need to make a shadow?
To make a shadow, you need a light source, an object to obstruct the light, and a surface for the shadow to be cast upon. The light source emits light, which is blocked by the object, creating the shadow on the surface behind it. The size and shape of the shadow can vary depending on the position of the light source and the object.
Why when the length and position of my shadow changes as i walk towards a light source and when i walk away from the lamp post?
Your shadow changes in length and position as you walk towards or away from a light source because the angle of the light hitting you changes. When you are closer to the light source, the angle is more direct, causing your shadow to appear shorter. As you move away, the angle becomes more oblique, resulting in a longer shadow.
How does an object create shadow?
An object creates a shadow when it blocks light from a source, such as the sun or a light bulb. The shadow is formed on the opposite side of the object from where the light is coming from. The size and shape of the shadow depend on the angle of the light source and the position of the object.
What cause the different shape of a shadow?
The shape of a shadow is determined by the angle and position of the light source, the object casting the shadow, and the surface on which the shadow falls. Changes in any of these factors can alter the shape of the shadow.
Why does the length and position of my shadow change as I walk towards a lamppost and away from the lamppost?
Light leaves the lamp and travels in straight lines from its point source. As you move away from the source, the angle between you and the light changes and this the length and position of your shadow changes.
Why does the length and position of my shadow change as I walk towards a lamp post and when I walk away from the lamp post?
The length and position of your shadow change as you walk towards a lamp post because you are moving closer to the light source, which creates a shorter shadow. Conversely, as you walk away from the lamp post, your shadow lengthens and changes position because you are moving further away from the light source, causing the shadow to stretch and shift.
What happens to a shadow when the object is moved?
The shadow's position changes relative to the light source and object. It will move and change in size depending on the direction and distance the object is moved.
