Real images are formed by ____

Options

A. converging rays
B. diverging rays
C. Both (a) and (b)
D. Neither (a) nor (b)

Answer

**Step-by-Step Solution:**

1. **Understanding Image Formation**:
- Images can be classified into two types: real images and virtual images. Real images are formed when light rays converge and actually meet at a point, whereas virtual images appear to diverge from a point where the rays do not actually meet.

2. **Identifying the Type of Ray**:
- Real images are formed by converging rays. A converging ray is one that comes together at a point after passing through a lens or reflecting off a mirror.

3. **Example of Converging Rays**:
- Consider a convex lens. When parallel rays of light enter a convex lens, they are refracted and converge at a point called the focus. The point where these rays meet is where the real image is formed.

4. **Diverging Rays**:
- On the other hand, diverging rays, such as those from a concave lens, spread apart after passing through the lens. These rays do not meet in real space, and thus, do not form a real image. Instead, they appear to come from a virtual point behind the lens.

5. **Conclusion**:
- Therefore, based on the behavior of light rays, we conclude that real images are formed by converging rays.

**Final Answer**: Real images are formed by **converging rays**.
