- When light from an electric bulb falls on a book, a part of it bounces off. This bouncing off of light by objects is called reflection of light. It's like how when you throw a ball against a wall, it bounces back to you.
- Light does the same thing when it hits objects like books or walls, bouncing off and reaching our eyes so we can see things around us.

Understanding Light Interaction with Objects
When light from an electric bulb falls on a book, several interactions can occur. Let's explore why option 'B' is the correct answer.
Reflection of Light
- When light hits the surface of the book, most of it does not penetrate the material.
- Instead, the light bounces off, a phenomenon known as reflection.
- This is why we can see the book; the reflected light travels to our eyes.
Why Other Options Are Incorrect
- Option A: Makes the book glow in the dark
- This is not true as the book does not emit light on its own when illuminated. It simply reflects light.
- Option C: Makes the book disappear
- Light does not make objects disappear. Instead, it allows us to see them more clearly.
- Option D: Changes the color of the book
- The color of the book appears the same unless the light is of a different wavelength (like colored light), but this is not a typical scenario with a standard bulb.
Conclusion
In summary, when light from an electric bulb falls on a book, it primarily bounces off the surface. This reflection allows us to perceive the book. Hence, the correct response is option 'B'. Understanding these principles of light can help us grasp how we see the world around us.
