A photon
a. is a quantum of light
b. is a wave
c. means bundle of energy(I think it's this one)
A photon is a quantum of light, meaning that it is discrete with characteristics of a particle and not a continuous wave.
The correct answer is a. A photon is indeed a quantum of light.
To understand why, let's break it down:
1. Definition: A photon is the smallest possible unit or particle of light. It is the basic unit of light energy.
2. Particle-Wave Duality: Light has characteristics of both a particle and a wave. This is known as the particle-wave duality of light. The concept of a photon helps us explain the particle aspect.
3. Quantum Theory: In quantum theory, light is described in terms of discrete packets of energy called photons. Photons are essentially bundles of energy that travel in a wave-like manner.
4. Measurement: When light interacts with matter, it behaves as if it consists of discrete particles. This particle nature of light is particularly evident when we try to measure it, for example, during the photoelectric effect or the emission and absorption of light by atoms.
So, to summarize, a photon is a term that describes the smallest possible quantity of light energy. It is a particle of light, and its existence helps us understand the particle aspect of light in the context of quantum mechanics.
