FAQs on NCERT Summary: Light, Shadow & Reflection - Science Class 6
| 1. What is the nature of light and how does it travel? |  |
| 2. How do shadows form and what factors affect their size? | |
Ans.Shadows form when an opaque object blocks the path of light. The size of a shadow depends on the distance of the object from the light source and the angle at which the light hits the object. Closer objects cast larger shadows, while the angle of light can stretch or shorten the shadow.
| 3. What is reflection and how does it occur in everyday life? | |
Ans.Reflection is the bouncing back of light when it hits a surface. This phenomenon occurs in everyday life, such as when we see our image in a mirror or when light reflects off water. The angle of incidence (the angle at which light hits a surface) is equal to the angle of reflection (the angle at which it bounces back).
| 4. What are the different types of mirrors and their uses? | |
Ans.The two main types of mirrors are plane mirrors and curved mirrors. Plane mirrors produce upright images and are commonly used in homes and bathrooms. Curved mirrors, such as concave and convex mirrors, have specific applications; concave mirrors are used in telescopes and makeup mirrors, while convex mirrors are used for safety in vehicles and stores.
| 5. How do we see colors and what role does light play in it? | |
Ans.We see colors because of the way light interacts with objects. Objects reflect certain wavelengths of light while absorbing others. The reflected light enters our eyes, and our brain interprets these wavelengths as different colors. For example, an object appears red because it reflects red wavelengths and absorbs other colors.
