Question

waves waves introduction which wave has the highest amplitude? (1 point)

Explanation:

Step1: Recall Amplitude Definition

Amplitude is the maximum displacement of a point on a wave from its rest position (the midline). Visually, it's the height from the midline to the peak (or trough) of the wave.

Step2: Compare the Three Waves

• The first wave (top) has a small height from the midline to its peak/trough.
• The second wave (middle) has a moderate height.
• The third wave (bottom) has a larger height from the midline to its peak/trough compared to the other two. Wait, no—wait, looking again: Wait, the first wave (top) has a larger vertical displacement (amplitude) than the middle? Wait, no, let's check the grid. Wait, the top wave: the peak is higher above the midline, and the trough is lower? Wait, no, the first wave (top) has a larger amplitude because the distance from the midline to the peak (or trough) is greater. Wait, no, maybe I misread. Wait, the first wave (top) has a single large "bump", the middle has smaller bumps, and the bottom has even smaller? Wait, no, the amplitude is the maximum distance from the equilibrium (midline). So the first wave (top) has a higher amplitude (larger vertical distance from midline) than the middle and bottom. Wait, but maybe the first wave (top) is the one with highest amplitude. Wait, let's re-express:

Looking at the three waves:

1. Top wave: The vertical distance from midline to peak (or trough) is the largest among the three.
2. Middle wave: Smaller vertical distance.
3. Bottom wave: Even smaller vertical distance (more frequent, smaller waves).

So the top wave has the highest amplitude. Wait, but the options are the three with radio buttons. Wait, the first option (top) has a larger amplitude. Wait, maybe I made a mistake. Wait, amplitude is the height, so the wave with the tallest peaks (and deepest troughs) relative to the midline has the highest amplitude. So the first wave (top) has a higher amplitude than the middle and bottom. So the answer is the first wave (the top one with the large, slow wave).

Answer:

The wave with the highest amplitude is the first one (the top - most wave with the larger, less - frequent oscillations).
