प्रश्न
While doing an experiment for the determination of focal length of a convex lens, Raja Suddenly dropped the lens. It got broken into two halves along the axis. If he continues his experiment with the same lens,
- can he get the image?
- Is there any change in the focal length?
उत्तर
- Yes, he can get the image, because the lens is broken into two halves along the axis.
- No, focal length remains the same for the lens if it’s broken (or) not broken.
