Final answer:
Waves cannot superimpose if their frequencies are different. Interference occurs when waves with different frequencies try to occupy the same space at the same time.
Step-by-step explanation:
False, waves cannot superimpose if their frequencies are different. When waves with different frequencies try to occupy the same space at the same time, they do not combine to form a new wave. Instead, they interfere with each other, causing a phenomenon called interference. This interference can result in the waves canceling each other out or creating regions of constructive or destructive interference.
