Question: Light is… Option 1: Electromagnetic Radiation This is true. Light is a form of electromagnetic radiation, meaning it consists of oscillating electric and magnetic fields that propagate through space. This categorization places light among the electromagnetic spectrum, which includes radio waves, visible light, X-rays, etc. The statement aligns with foundational physics. Option 2: Measurable in kelvins (as a temperature) This is misleading. Kelvins measure temperature, not light itself. While you can discuss the temperature of a light source (like a filament or the ambient temperature related to a light-emitting object) or assign a color temperature to light (which describes the spectral composition in a way related to blackbody radiation), light itself is not quantified by a temperature value as an intrinsic property. So this claim is not correct in the sense of describing light per se. Option 3: A wave (or behaves like one); it has flow and directionality This statement is also true. Light exhibits wave-like properties such as interference, diffraction, and polarization, and it propagates with a direction (flow) through space. While light also has particle-like aspects (photons) in quantum descriptions, its wave behavior and directional propagation are well-established features.
