Convex Mirror and Divergence of Light
A convex mirror is designed with a reflective surface that curves outward. This unique shape significantly influences how light behaves when it reflects off the surface.
- Diverging Light Rays:
- When parallel light rays strike a convex mirror, they reflect outward.
- The reflected rays appear to diverge from a common focal point behind the mirror.
- This creates a wider field of view, making convex mirrors ideal for applications like vehicle side mirrors.
- Virtual Image Formation:
- The images produced are virtual, meaning they cannot be projected on a screen.
- These images are smaller and upright, providing a broader perspective.
Convex Lens and Convergence of Light
In contrast, a convex lens has a shape that is thicker in the middle and tapers toward the edges. This design affects light rays passing through it.
- Converging Light Rays:
- When parallel light rays enter a convex lens, they refract and converge to a focal point on the opposite side.
- This property is due to the lens's curvature, which bends the light towards the center.
- Real Image Formation:
- Convex lenses can produce real images, which can be projected onto a screen.
- The images can be larger or smaller depending on the object's distance from the lens.
