👉 The defense-light particle theory posits that light is composed of discrete, massless particles known as photons. These particles are fundamental to explaining various optical phenomena, such as the photoelectric effect and the behavior of light in different media. Unlike classical wave theories, which struggle to account for the energy quantization observed in these interactions, the photon model offers a clear explanation: when light strikes a material, it transfers energy in packets (photons) proportional to the light's frequency. This particle nature of light is crucial for understanding phenomena like absorption and emission spectra, where specific wavelengths are absorbed or emitted by atoms and molecules. By framing light as particles, this theory aligns with quantum mechanics, providing a robust framework for explaining both theoretical and experimental observations in physics.
