Activity 1. “Name My Parts” Direction: Label the parts of a wave. Crest amplitude trough resting state wave length 4. 3. 2. 5.
The Correct Answer and Explanation is:
Here are the correct labels for the wave diagram based on the numbered positions:
- 1. Crest
- 2. Trough
- 3. Amplitude
- 4. Wavelength
- 5. Resting state
A wave is a rhythmic disturbance that transfers energy through a medium or space. It can be mechanical, like sound and water waves, or electromagnetic, like light and radio waves. The image shows a transverse wave, where the oscillations occur perpendicular to the direction of wave propagation.
The crest is the highest point the wave reaches above the resting level. It reflects the peak of energy in a single oscillation. In contrast, the trough is the lowest point below the resting level, signifying the maximum downward displacement.
The amplitude is the vertical distance from the resting position to either the crest or the trough. It indicates the wave’s energy; greater amplitude means more energy carried by the wave.
The wavelength is the horizontal length between two successive points in phase on the wave, such as crest to crest or trough to trough. It defines the distance a wave covers in one complete cycle and is crucial for determining wave speed and frequency.
The resting state is the baseline from which the wave rises and falls. It represents the undisturbed condition of the medium, assuming no energy is passing through it.
Understanding these components is essential in physics and engineering. These concepts allow scientists to analyze various phenomena, from interference patterns in optics to medical imaging using ultrasound. By dissecting the anatomy of a wave, learners build a foundation for deeper study of sound, light, and other wave-based technologies.
