Step-by-step solution for: Properties of Waves Worksheet - Flying Colors Science
Let’s go through each question on the worksheet step by step.
---
1. What is a wave?
A wave is a way energy moves from one place to another without moving matter (like water or air) along with it. Think of when you shake a rope — the bump travels down the rope, but the rope itself doesn’t move forward. That bump is a wave carrying energy.
✔ Final Answer for #1:
A wave is a disturbance that transfers energy from one place to another without transferring matter.

2. What are the two types of mechanical waves? Briefly describe each.
Mechanical waves need something to travel through — like air, water, or a solid. There are two main kinds:
- Transverse waves: The particles move up and down (or side to side), perpendicular to the direction the wave is going. Example: shaking a rope up and down — the wave goes left/right, but the rope moves up/down.
- Longitudinal waves: The particles move back and forth in the same direction the wave is traveling. Example: sound waves — air molecules squish together and spread out as the wave moves.
✔ Final Answer for #2:
The two types are transverse waves (particles move perpendicular to wave direction) and longitudinal waves (particles move parallel to wave direction).

3. What is a medium? Give 3 examples of mediums.
A medium is the material or substance that a wave travels through. Without a medium, mechanical waves can’t move. For example, sound needs air, water, or solids to travel — it can’t go through empty space.
Three examples:
- Air (for sound waves)
- Water (for ocean waves or underwater sound)
- Steel or metal (for vibrations in bridges or rails)
✔ Final Answer for #3:
A medium is the material a wave travels through. Examples: air, water, steel.

4. Each term corresponds to either longitudinal (“L”) or transverse (“T”) waves. Write “L” or “T”.
Let’s match each term:
- parallel motion → This means particles move in the same direction as the wave. That’s longitudinal. → L
- compressions and rarefactions → These are the squeezed and stretched parts of a longitudinal wave (like in sound). → L
- crests → The high points of a transverse wave (like peaks on a rope wave). → T
- sound → Sound waves are longitudinal. → L
- light → Light is an electromagnetic wave, which is transverse. (Note: light isn’t mechanical, but if we’re classifying its wave type, it’s transverse.) → T
- travels at 90° angles → Means particle motion is perpendicular to wave direction → transverse → T
- troughs → Low points of a transverse wave → T
✔ Final Answer for #4:
parallel motion — L
compressions and rarefactions — L
crests — T
sound — L
light — T
travels at 90° angles — T
troughs — T

Final Answer:
1. A wave is a disturbance that transfers energy from one place to another without transferring matter.
2. Transverse waves (particles move perpendicular to wave direction) and longitudinal waves (particles move parallel to wave direction).
3. A medium is the material a wave travels through. Examples: air, water, steel.
4. parallel motion — L; compressions and rarefactions — L; crests — T; sound — L; light — T; travels at 90° angles — T; troughs — T
