Wave Energy

Front

Oscillation Noun

---

[os-uh-ley-shuhn]

Back

Oscillation

---

A repeating up-and-down or back-and-forth motion that follows a consistent pattern around a central point or equilibrium.

---

Example: The image shows a wave oscillating up and down around a central line, demonstrating oscillation.

Front

Crest Noun

---

[krest]

Back

Crest

---

The highest point or peak of a wave, representing the maximum upward displacement from the resting position.

---

Example: The crest is the highest point of the wave, showing maximum upward displacement.

Front

Trough Noun

---

[trof]

Back

Trough

---

The lowest point or valley of a wave, representing the maximum downward displacement from the resting position.

---

Example: The diagram shows a wave with the trough labeled as the lowest point, helping students understand wave structure.

Front

Still Water Level Noun

---

[stil waw-ter lev-uhl]

Back

Still Water Level

---

The level of a body of water when it is at rest, serving as the equilibrium or resting line.

---

Example: The image shows water in a tube at the same level on both sides, illustrating the still water level.

Front

Nodes Noun

---

[nohdz]

Back

Nodes

---

The points on a wave that have zero amplitude, where the wave crosses the equilibrium or resting line.

---

Example: The image shows nodes on a wave where it crosses the equilibrium line, indicating zero amplitude.

Front

Wavelength Noun

---

[weyv-lengkth]

Back

Wavelength

---

The distance between two consecutive corresponding points of a wave, such as from one crest to the next.

---

Example: The image shows the distance between two crests of a wave, illustrating 'wavelength'.

Front

Amplitude Noun

---

[am-pli-tood]

Back

Amplitude

---

The maximum displacement of a wave from its resting position, indicating the wave's intensity or energy.

---

Example: The image shows amplitude as the height from the wave's resting position to its crest, explaining wave intensity.

Front

Kinetic Energy Noun

---

[ki-net-ik en-er-jee]

Back

Kinetic Energy

---

The energy an object possesses due to its motion, which increases with the object's mass and speed.

---

Example: A moving ball in Newton's cradle shows kinetic energy transferring to stationary balls.

Front

Surface Wave Noun

---

[sur-fis weyv]

Back

Surface Wave

---

A mechanical wave that propagates along the interface between two different media, such as an ocean wave.

---

Example: The image shows a surface wave on the ocean, highlighting wave crest, trough, and direction of travel.

Front

Tsunami Noun

---

[tsoo-nah-mee]

Back

Tsunami

---

A series of powerful ocean waves with very long wavelengths, typically caused by underwater earthquakes or volcanic eruptions.

---

Example: An underwater earthquake displaces water, creating waves that grow as they reach the shore.
