Question on: SS1 Physics - Modern Physics

The wave-particle duality of light and matter has significant implications for our understanding of their behaviour. It implies that particles, such as electrons, can exist in superposition states, where they can simultaneously occupy multiple locations or energy states. This is crucial for understanding phenomena like quantum tunnelling and quantum entanglement.

Additionally, the wave-like properties of light and matter explain various interference and diffraction phenomena, such as Young's double-slit experiment and the formation of interference patterns. On the other hand, the particle-like nature of light and matter explains phenomena such as the photoelectric effect, where light can eject electrons from a material. Overall, the wave-particle duality provides a comprehensive framework to describe and explain the behaviour of light and matter at both microscopic and macroscopic levels.
