What happens when light hits a lens?

• A. Absorption, condensation, decomposition
• B. Absorption, transmission, reflection
• C. Absorption, scattering, brightness
• D. Absorption, distortion, magnification

Answer: (B)

When light strikes a lens, it undergoes three primary interactions: absorption, transmission, and reflection. First, some light may be absorbed by the material of the lens, depending on the lens's composition and the wavelength of the light. This absorption can lead to a small loss of intensity. However, a larger portion of the light will be transmitted through the lens, allowing it to pass through and refract or bend due to the lens's shape. This refraction is what makes lenses useful for focusing light, as they change the direction of the light rays to converge or diverge, which is essential in applications such as glasses, cameras, and telescopes. In addition to transmission, a portion of the light may be reflected off the surface of the lens. This reflection can vary depending on the lens's surface coating and the angle of incident light. The combined effects of these three interactions—absorption, transmission, and reflection—determine how effectively a lens can manipulate light, which is critical to its functionality in various optical devices.
