Final answer:
The statement is true; waves with different frequencies can superimpose, resulting in various interference patterns. Comprehension, whether in reading or listening, relies on strategies and cognitive skills rather than the format of material. Flexibility and openness to interpretations aid in understanding complex subjects. The correct option is A.
Step-by-step explanation:
The statement that waves can superimpose if their frequencies are different is true. Superposition is the principle that when two or more waves meet at a point, the resultant wave is the sum of the individual waves. Therefore, it doesn't matter if the waves have different frequencies; they will still superimpose. However, their interaction can lead to various phenomena such as beats or interference patterns.
Similarly, the statement regarding the amplitude of one wave being affected by another is also true but only when they are in phase alignment, which is known as constructive interference, leading to an increase in the amplitude of the resultant wave. On the other hand, destructive interference occurs when waves are out of phase, which can result in a decrease in amplitude or even cancellation.
When it comes to reading comprehension and listening comprehension, the ability to understand material is not solely dependent on the format (printed book or audio book)—it also relies on the individual's familiarity with the subject matter and cognitive strategies employed for comprehension, critical analysis, and evaluation.
Strategies to improve comprehension include looking up unknown words, taking notes, asking questions, and consulting credible sources for information. The flexibility and openness to multiple interpretations are essential for developing a nuanced understanding of complex texts.
