Step-by-step solution for: 25192225.doc - WORKSHEET - LABELING WAVES 1. The highest point on ...
Let’s go through each question one by one. I’ll explain what you need to know and then give the correct answer.
---
1. The highest point on a wave is called the ______, while the lowest point is a ______.
Think of a wave like ocean waves — the top part that sticks up high is the “crest,” and the bottom dip is the “trough.”
→ Answer: crest, trough
---
2. The ______ of a wave is a measure of the amount of energy it carries.
The taller the wave (from middle to top), the more energy it has. That height is called the “amplitude.”
→ Answer: amplitude
---
3. The distance from the crest of one wave to the crest of the next wave is the ______.
This is how long one full wave is — we call this the “wavelength.” You can also measure from trough to trough — same thing.
→ Answer: wavelength
---
4. The number of waves that pass a given point per second is the ______.
If 5 waves go past you every second, the frequency is 5 per second. We call this “frequency.”
→ Answer: frequency
---
5. Use the diagram below to label the following parts:
Looking at the wave drawing:
- A = from middle to top → that’s amplitude
- B = from one crest to next crest → that’s wavelength
- C = the very top → that’s crest
- D = the very bottom → that’s trough
→ Answers:
A. Amplitude
B. Wavelength
C. Crest
D. Trough
---
6. Look at the illustrations of waves shown above. Answer the following questions:
We have four wave drawings labeled P, Q, R, S.
a) Which wave has the greatest amplitude?
Amplitude = height from center to peak. Wave R is tallest → so it has greatest amplitude.
b) Which wave has the smallest amplitude?
Wave S is shortest → smallest amplitude.
c) Which wave has the longest wavelength?
Wavelength = distance between two crests. Wave P has the most stretched-out waves → longest wavelength.
d) Which wave has the shortest wavelength?
Wave Q has squished-together waves → shortest wavelength.
→ Answers:
a) R
b) S
c) P
d) Q

7. What is a medium in terms of waves?
A medium is just the stuff the wave travels through — like air for sound, water for ocean waves, or even a rope if you shake it.
→ Answer: The material through which a wave travels.
---
8. Sound is a type of wave that requires a ______ to travel.
Sound needs something to move through — like air, water, or solid objects. It can’t travel in empty space (like outer space). So it needs a “medium.”
→ Answer: medium
---
9. When a wave enters a new medium, its ______ changes but its ______ remains constant.
When a wave goes from air into water, for example, its speed and wavelength change — but the frequency stays the same. Frequency depends on the source, not the medium.
→ Answer: speed (or wavelength), frequency
*(Note: Either “speed” or “wavelength” can go first — both change. But frequency always stays the same.)*
---
10. Waves ______ when they encounter an obstacle or opening comparable in size to their wavelength.
This is called “diffraction” — when waves bend around corners or spread out after going through a small hole.
→ Answer: diffract
---
11. What ______ occurs when two waves combine to form a larger amplitude?
When two waves line up perfectly (peaks with peaks), they add together and make a bigger wave. This is called “constructive interference.”
→ Answer: constructive interference
---
12. What ______ occurs when two waves combine to cancel each other out?
When a peak meets a trough, they cancel — making no wave or a smaller one. This is “destructive interference.”
→ Answer: destructive interference
---
13. In transverse waves, particles move ______ to the direction of the wave.
In transverse waves (like shaking a rope up and down), the particles move perpendicular — meaning at right angles — to the direction the wave is moving.
→ Answer: perpendicular
---
14. Label the parts of the longitudinal wave shown below:
Longitudinal waves (like sound) have compressions (where particles are squeezed together) and rarefactions (where they’re spread apart).
Looking at the diagram:
- A = where lines are close together → compression
- B = where lines are far apart → rarefaction
- C = distance between two compressions → wavelength
→ Answers:
A. Compression
B. Rarefaction
C. Wavelength
---
Final Answer:
1. crest, trough
2. amplitude
3. wavelength
4. frequency
5. A. Amplitude, B. Wavelength, C. Crest, D. Trough
6. a) R, b) S, c) P, d) Q
7. The material through which a wave travels.
8. medium
9. speed (or wavelength), frequency
10. diffract
11. constructive interference
12. destructive interference
13. perpendicular
14. A. Compression, B. Rarefaction, C. Wavelength
