What field of study focuses on light?

  1. Acoustics

  2. Optics

  3. Thermodynamics

  4. Electromagnetism

The correct answer is: Optics

The correct response is indeed related to the study of light, which is the primary focus of optics. Optics is the branch of physics that deals with the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it, such as lenses, mirrors, and optical fibers. While the other fields mentioned do intersect with certain aspects of light, they do not primarily focus on light as their central theme. Acoustics studies sound and its properties, thermodynamics relates to heat and energy transformations, and electromagnetism concentrates on electric and magnetic fields, including electromagnetic waves that encompass light, but not exclusively so. Thus, optics is the most appropriate field of study when specifically considering light.
