What happens to a shadow when you move the object closer to the light ...
When an object is moved closer to the light source, the shadow gets smaller.
Explanation:
When an object blocks the path of light, it creates a shadow behind it. The size of the shadow depends on the distance between the object and the light source. Let's understand why the shadow gets smaller when the object is moved closer to the light source:
1. Nature of Light:
Light travels in straight lines. When light rays encounter an object, they cannot pass through it and create an area of darkness behind it, known as a shadow. The size and shape of the shadow are determined by the position of the object and the direction of the light source.
2. Proportional Relationship:
The size of a shadow is directly related to the distance between the object and the light source. As the object is moved closer to the light source, the distance between the object and the light source decreases. This change in distance affects the size of the shadow.
3. Light Spreading Out:
When light rays are emitted from a single point source, they spread out in all directions. As the light rays diverge or spread out, they cover a larger area. So, when the object is closer to the light source, the light rays diverge less, resulting in a smaller area of shadow being created.
4. Angle of Light:
The angle at which the light rays hit the object also affects the size of the shadow. When the object is closer to the light source, the angle of the light rays hitting the object becomes steeper. This causes the shadow to be shorter and smaller compared to when the object is farther away.
5. Conclusion:
In conclusion, when the object is moved closer to the light source, the shadow gets smaller because the distance between the object and the light source decreases. The light rays diverge less, and the angle of incidence becomes steeper, resulting in a smaller shadow being cast.
