Making Waves, Lesson Plans - The Mailbox - Free Printable

Let's solve the worksheet titled "Making Waves" step by step using the provided word bank and the diagram.

---

Word Bank:

- amplitude
- frequency
- transverse
- wavelength
- sound
- energy
- trough
- longitudinal
- wave
- crest
- hertz
- cycle

---

Now, let’s go through each sentence and fill in the blanks with the correct word from the word bank. Then we'll label the diagram accordingly.

---

1. E________ travels in waves.

We’re looking for something that travels in waves. The word energy fits here because energy is transferred through waves (e.g., sound waves, light waves).

✔ Answer: Energy

> 1. Energy travels in waves.

---

2. Transverse waves move up and down in patterns that have high points called a ________.

Transverse waves have peaks and troughs. The high points are called crests.

✔ Answer: crest

> 2. Transverse waves move up and down in patterns that have high points called a crest.

---

3. The low points of a transverse wave are called _________.

Low points = troughs

✔ Answer: trough

> 3. The low points of a transverse wave are called troughs.

---

4. The distance between any two troughs or peaks is called the ________.

This is the definition of wavelength — the distance between two consecutive crests or troughs.

✔ Answer: wavelength

> 4. The distance between any two troughs or peaks is called the wavelength.

---

5. The height of a peak or trough is called the ________.

The height from the rest position to the peak is called amplitude.

✔ Answer: amplitude

> 5. The height of a peak or trough is called the amplitude.

---

6. ________ is the number of complete waves that pass by in one second.

This is the definition of frequency.

✔ Answer: Frequency

> 6. Frequency is the number of complete waves that pass by in one second.

---

7. Frequency is measured in ________, (which is written Hz).

The unit of frequency is hertz, abbreviated as Hz.

✔ Answer: hertz

> 7. Frequency is measured in hertz, (which is written Hz).

---

8. L________ waves move by pushing forward and pulling back.

These are longitudinal waves, like sound waves, where particles move parallel to the direction of the wave.

✔ Answer: Longitudinal

> 8. Longitudinal waves move by pushing forward and pulling back.

---

9. O________ waves are examples of longitudinal waves.

Sound waves are a classic example of longitudinal waves.

✔ Answer: Sound

> 9. Sound waves are examples of longitudinal waves.

---

10. Waves on the surface of water are examples of ________ waves.

Water waves are transverse waves — they move up and down while the wave travels forward.

✔ Answer: transverse

> 10. Waves on the surface of water are examples of transverse waves.

Diagram Labeling (a):

This diagram shows a transverse wave with labeled parts:

- a: This is the resting position (already labeled).
- b: The high point → crest
- c: The low point → trough
- d: The distance between two crests → wavelength
- e: The height from resting position to crest → amplitude

So labeling:
- b = crest
- c = trough
- d = wavelength
- e = amplitude

---

Diagram (f):

This is a longitudinal wave (compressions and rarefactions). It's labeled as:

- f = longitudinal wave

And it's shown with compressions (dense areas) and rarefactions (spread out areas), typical of sound waves.

✔ So, f = longitudinal wave

---

✔ Final Answers:

1. Energy
2. crest
3. troughs
4. wavelength
5. amplitude
6. Frequency
7. hertz
8. Longitudinal
9. Sound
10. transverse

---

🔤 Diagram Labels:

- b: crest
- c: trough
- d: wavelength
- e: amplitude
- f: longitudinal wave

📌 Summary:

This worksheet teaches key wave concepts:
- Transverse waves have crests and troughs.
- Longitudinal waves involve compressions and rarefactions.
- Key terms include amplitude, wavelength, frequency, and energy transfer.

All answers use words from the word bank and match scientific definitions.
