FAQs on Light Shadow and Reflections Class 6 Worksheet Science

1. What is the difference between light, shadow, and reflections?
Ans. Light is a form of energy that illuminates objects, creating shadows when the light is blocked by an object. Reflection occurs when light bounces off a surface.
2. How are shadows formed?
Ans. Shadows are formed when an object blocks the path of light, creating a dark area behind it where light cannot reach.
3. Can shadows change in size and shape?
Ans. Yes, shadows can change in size and shape depending on the position of the light source, the distance between the object and the surface, and the angle at which the light hits the object.
4. What is the law of reflection?
Ans. The law of reflection states that the angle of incidence is equal to the angle of reflection. This means that the angle at which light hits a surface is the same as the angle at which it bounces off the surface.
5. How can we use reflections in everyday life?
Ans. Reflections are commonly used in mirrors, lenses, and other optical devices. They help us see images of objects and ourselves, and are essential in photography, astronomy, and many other fields.
