All particles have a wave nature, as described by the concept of wave-particle duality in quantum mechanics. This means that particles, such as electrons and photons, can exhibit both particle-like and wave-like behavior depending on the experimental setup. On the other hand, not all waves have a particle nature. Classical waves, such as sound waves and water waves, do not exhibit particle-like behavior. Therefore, while all particles have a wave nature, not all waves have a particle nature. **
