What does a ray diagram typically illustrate?

• A. The wavelength of light in different media
• B. The color spectrum of light
• C. How light travels through lenses or mirrors
• D. The temperature of light in various conditions

Answer: (C)

A ray diagram is a visual tool used in optics to represent how light rays travel through optical elements such as lenses and mirrors. It diagrams the path of light as it encounters these surfaces, illustrating the angles of incidence, reflection, and refraction. This helps in understanding the behavior of light, including how images are formed, magnification, and the focal points of various optical devices. When drawing a ray diagram for a lens, for example, one can demonstrate how parallel rays entering a convex lens converge to a focal point, resulting in a real image. For concave mirrors, the diagram shows how incoming parallel rays reflect and diverge, making it easier to grasp the concepts of virtual images and magnification. Thus, the primary purpose of a ray diagram is to facilitate the comprehension of the interaction between light and optical elements, making option C the correct answer.
