FAQs on Light and Shadow - 2 Class 2 Worksheet Science

1. What is light and shadow?
Ans. Light is a form of energy that enables us to see objects. Shadows are formed when an object blocks the path of light, resulting in a dark area behind the object where light cannot reach.
2. How does light travel?
Ans. Light travels in straight lines called rays. It can travel through transparent materials such as air, water, and glass. When light hits an opaque object, it is either absorbed or reflected.
3. What causes shadows to form?
Ans. Shadows are formed when an object blocks the path of light. The light rays cannot pass through the object and create a dark area behind it. The size and shape of the shadow depend on the position and size of the light source, as well as the distance between the object and the surface where the shadow is cast.
4. Can shadows change in size and shape?
Ans. Yes, shadows can change in size and shape depending on the position of the object, light source, and surface where the shadow is cast. When the object moves closer to the light source, the shadow becomes larger. Conversely, when the object moves farther away from the light source, the shadow becomes smaller. The shape of the shadow can also change depending on the angle at which the light rays hit the object.
5. How is light used in daily life?
Ans. Light has numerous applications in our daily lives. It allows us to see objects, provides illumination for various activities, and is used in technologies such as lamps, flashlights, and headlights. Light is also essential for photosynthesis in plants, communication through fiber optics, and various medical and scientific procedures like laser surgeries and microscopy.
