Final answer:
The statements about constructive and destructive interference and wave superposition of different frequencies being possible are true. The concept of wave-particle duality applies to quantum, not macroscopic, scales making that statement false.
Step-by-step explanation:
The statement that the two types of interference are constructive and destructive interferences is true. When two waves meet, they can interfere either constructively, where the amplitudes add to each other, or destructively, where they subtract from each other, sometimes completely canceling each other out if they're of equal amplitude and opposite phase.Wave superposition of differing frequencies is also true. Waves of different frequencies can overlap and combine temporarily, which is essential for phenomena such as beats in acoustics. However, their individual frequencies do not change as a result of their interference.The statement about wave-particle duality existing for macroscopic objects is false. Wave-particle duality is a concept in quantum mechanics that applies to microscopic particles, like electrons and photons, not to macroscopic objects like rocks and balls.
