ViviYes, the formation of a standing wave requires the interference of two waves traveling in opposite directions with the same frequency and amplitude. This interference causes certain points, called nodes and antinodes, to remain stationary while the rest of the medium oscillates.

If wave a carries more energy than wave b then wave b has a smaller what?
If wave A carries more energy than wave B, then wave B has a smaller amplitude, frequency, or wavelength compared to wave A. This means that the properties of wave B are lesser in magnitude than those of wave A.
What part of wave b is passing the reef when t timer is stopped?
The crest of wave b is passing the reef when the timer is stopped.
What will occur when the trough of Wave A overlaps the trough of Wave B?
When the trough of Wave A overlaps the trough of Wave B, the two troughs will combine to create a larger and deeper trough, increasing the amplitude of the resulting wave. This phenomenon is known as constructive interference and results in a more significant wave.
What will occur when the trough of Wave A overlaps the crest of Wave B?
When the trough of Wave A overlaps the crest of Wave B, they will cancel each other out in a process called destructive interference. This will result in a reduction or complete elimination of the amplitude of the resulting wave in that specific region.
What is the distance from the rest position in a wave to the crest or trough?
Let us look at a cosine wave, described by y = A cos (b). When b = 0 degrees, y = A (<-- peak) When b = 90 degrees, y = 0 (<-- rest position of the wave) When b = 180 degrees, y = -A (<-- trough) When b = 270 degrees, y=0 (<-- rest position again) and so on. If we force A to be a function of time, then the wave becomes a standing wave (see the related link). The peak and trough will reverse their relative position for every half of a period. Regardless, the trough at any time and the rest position is still 90 degrees, or one quarter of a wavelength. ====================================
