Converging Lens Ray Diagram Steps:

• Recall that a converging lens refracts parallel rays toward a focal point on the opposite side.
• Identify diagrams where incoming parallel rays bend inward after the lens.
• Check for principal rays: one parallel to axis through focal point, one through center undeviated.
• Select the diagram matching these convergence paths.

Why B is correct:

• Rays converge to a focal point after the lens, as per the lens formula where positive focal length indicates convergence for real images.

Why the others are wrong:

• A: Rays diverge after the lens, characteristic of a diverging lens.
• C: Rays remain parallel post-lens, showing no refraction.
• D: Rays converge before the lens, violating Snell's law of refraction direction.

Final answer: B
