EXPLANATION
Question: Which branch of physics studies the properties of light and its interaction with matter?
- a) Electrodynamics
- b) Nuclear physics
- c) Optics
- d) Plasma physics
ANSWER: c) Optics
EXPLANATION:
The branch of physics that studies the properties of light and its interaction with matter is c) Optics. Optics is the field of physics that deals with the behavior and properties of light, including its generation, propagation, and detection. It encompasses the study of phenomena such as reflection, refraction, diffraction, interference, and polarization of light. Optics also examines the interaction of light with various materials and the devices and instruments used to manipulate and measure light. Electrodynamics, on the other hand, is a broader branch of physics that deals with the study of electric and magnetic fields and their interactions. Nuclear physics focuses on the study of atomic nuclei and their interactions, while plasma physics deals with the behavior and properties of ionized gases, known as plasmas.
