FAQs on What is a Shadow? Video Lecture - Class 6
| 1. What is a shadow? |  |
Ans. A shadow is a dark area or shape that is formed when an object blocks the light. It is created because light cannot pass through the object, resulting in a lack of illumination on the surface behind it.
| 2. How is a shadow formed? | |
Ans. A shadow is formed when an object comes between a light source and a surface. The object blocks some or all of the light, preventing it from reaching the surface directly behind it. As a result, a shadow is cast on the surface opposite to the light source.
| 3. Why does the size of a shadow change? | |
Ans. The size of a shadow changes based on the position of the light source and the object casting the shadow. When the light source moves closer to the object, the shadow becomes larger. Conversely, when the light source moves farther away, the shadow becomes smaller. The size of the object also affects the size of the shadow.
| 4. Can a shadow have different shapes? | |
Ans. Yes, a shadow can have different shapes depending on the shape of the object casting it. The shape of the shadow mirrors the shape of the object, but it may appear distorted or elongated depending on the angle and direction of the light source.
| 5. What is the significance of shadows? | |
Ans. Shadows have various significance in different contexts. They can provide important information about the position of objects and their relationships with light sources. Shadows are also used in artistic compositions to create depth and visual interest. Additionally, shadows play a role in scientific studies, such as measuring the height of objects or determining the Earth's rotation.
