👉 The graph depicting light particles, often referred to as photons, illustrates the fundamental nature of light as both a wave and a particle. On one axis, we typically see the frequency or energy of the light, while the other axis represents the intensity or number of photons. The graph shows discrete peaks corresponding to specific energy levels, which align with the particle nature of light, where each peak represents a photon carrying a quantized amount of energy. These peaks are spaced at intervals determined by Planck's equation (E = hν), where E is the energy, h is Planck's constant, and ν is the frequency. On the other hand, the graph also includes a continuous waveform, representing the wave-like properties of light, such as diffraction and interference patterns. These wave-like features are evident in the smooth, sinusoidal curve, which is characteristic of electromagnetic waves. The waveform's amplitude corresponds to the intensity of the light, showing how the energy of the photons varies with the number of particles (photons) present. Together, these two representations—discrete peaks for particle-like behavior and a continuous wave for wave-like behavior—demonstrate the dual nature of light, encapsulating both its particle and wave characteristics as described by quantum mechanics. This duality is a cornerstone concept in understanding phenomena like the photoelectric effect and quantum entanglement.
