Final answer:
To emphasize the ridge in a fiver wave, you would press the ridge inwards.
Step-by-step explanation:
To emphasize the ridge in a wave, you would press the ridge inwards. When a wave is formed, it consists of crests (the highest points of the wave) and troughs (the lowest points of the wave). The ridge refers to the area of the wave between adjacent crests or troughs. By pressing the ridge inwards, you are effectively increasing the amplitude of the wave at that point, thus emphasizing the ridge.
The fill-in table task requires measuring the distance from the equilibrium point to each crest and trough of the wave to determine the wave's amplitude. The details about the fifth dot suggest a specific position on a diagram or in an experiment where measurement is to be taken.
The strategy hint implies consideration of wave behavior, particularly reflection, and interference, which are phenomena that affect how waves combine and emphasize certain areas such as ridges or crests. Additionally, the student is reminded that waves have a consistent shape and that upon reflection, the waves will overlap before receding, which can help visualize the points of emphasis on the waveform.
To emphasize the ridge in a wave, press the ridge inwards to increase the amplitude at that point.
