Final answer:
If the described waves pass the same point at the same time, constructive interference would occur, resulting in a wave with twice the amplitude but the same wavelength. Option A is correct.
Step-by-step explanation:
If two transverse waves with the same wavelength are starting high, going down to a trough and repeating two times, and these are passing the same point at the same time, we can expect a type of interaction known as constructive interference.
This occurs when the waves are exactly in phase, which means the crests of one wave align with the crests of the other, and the troughs do the same. The result is a new wave pattern that has twice the amplitude of the individual waves, while maintaining the same wavelength.
The wave interaction described in the question is an example of constructive interference.
Constructive interference occurs when two waves with the same wavelength and amplitude meet and reinforce each other, resulting in a wave with a larger amplitude. In this case, both waves start high before going down to a trough and repeating two times, which means their crests and troughs align, creating constructive interference.
Examples of constructive interference include the formation of standing waves and the phenomenon of beats in sound waves.
