photon theory

Photon theory posits that light is made up of tiny packets of energy called photons. Rather than being continuous waves, photons behave like discrete particles that can travel through space. Each photon carries a specific amount of energy, which is related to its color or frequency; for example, blue light has more energetic photons than red light. This theory helps explain various phenomena in physics, such as the photoelectric effect, where light can cause electrons to be emitted from materials. Overall, photons play a crucial role in our understanding of light and its interactions with matter.
