Light comes in discrete quanta, not continuous waves
This discovery led to the understanding that light energy is quantized, which was a pivotal moment in the development of quantum mechanics and had significant implications for modern technology.
Understanding light as quantized energy is crucial for advancements in quantum physics and electronic devices.
