Which statement about a spherical lens is true?

Which statement about a spherical lens is true?

• A. A spherical lens deviates rays of light in more than one direction.
• B. A spherical lens deviates rays of light in the same direction.
• C. A spherical lens bends light at varying speeds.
• D. A spherical lens cannot focus light.

Answer: (B)

Light is bent when it passes through a lens, and for a spherical surface the common way we describe it is that rays are refracted so they come together toward a single focal point after exiting. In that simplified, paraxial view, the refracted rays are directed toward the same general direction toward the focus, which is why this statement fits best. Real lenses can show spherical aberration for rays far from the axis, but the typical expectation is convergence toward one focal direction. The other ideas don’t match the standard description: refraction isn’t about bending at varying speeds in the sense stated, and a spherical lens can indeed focus light.
