Final answer:
The statement about constructive and destructive interference being the two types of interference is true. Wave-particle duality exists only in the quantum realm and not on the macroscopic scale, making the second statement false.
Step-by-step explanation:
Wave Mechanics and Constructive/Destructive Interference
The statement regarding the two types of interference in wave mechanics is true. There are indeed two primary types of interference: constructive and destructive interference. Constructive interference occurs when waves come together in such a way that they are in phase, and their amplitudes add together to form a wave of greater amplitude. Destructive interference, on the other hand, happens when waves are out of phase, and the crest of one wave aligns with the trough of another, reducing or canceling out the amplitude.
Wave-Particle Duality on the Macroscopic Scale
The concept of wave-particle duality is a fundamental principle in quantum mechanics, but it does not extend to objects on the macroscopic scale. Thus, the statement regarding wave-particle duality existing for objects on a macroscopic scale is false. This principle primarily applies to the micro-world, such as electrons and photons, where particles exhibit both wave-like and particle-like properties. However, in the macroscopic world that we experience daily, objects do not exhibit this duality.
