Study Notes
Module L: Waves and their Applications
- Module covers waves and their applications
- Unit 1: Waves
Day 1 - Lesson 1: Introduction to Waves
-
Standards:
- MS-PS4-1: Using mathematical representations to describe a simple wave model, including how amplitude relates to wave energy.
- MS-PS4-2: Developing and using a model to describe wave reflection, absorption, or transmission through different materials.
-
Objectives:
- Define wave
- Give examples of mediums
- Categorize waves as needing or not needing a medium
- Compare and contrast mechanical and electromagnetic waves
Vocabulary
- wave
- medium
- mechanical wave
- electromagnetic wave
Starter (Engage)
- Study a picture of a wave on water
- Answer questions about what waves are
What are Waves?
- A wave is a repeating disturbance that transfers energy from place to place
- Examples: light waves, sound waves, water waves
Wave Transfer Energy
- A wave transfers energy in the direction it travels
- The wave in the picture travels to the right, so energy is transferred to the right
Medium
- A medium is a matter through which a wave travels
- Examples: air, liquid, solid
- Mechanical waves travel through a medium (matter)
- Electromagnetic waves don't need a medium to travel
Check Your Understanding
- Categorize waves as mechanical or electromagnetic, and explain why:
- Water wave - Mechanical
- Sound wave - Mechanical
- Light wave - Electromagnetic
- Wave on spring/slinky - Mechanical
Day 2 - Lesson 1 (Continued): Types of Waves
-
Standards:
- MS-PS4-1: Using mathematical representations to describe a simple wave model, including how amplitude relates to wave energy.
- MS-PS4-2: Developing and using a model to describe wave reflection, absorption, or transmission through different materials.
-
Objectives:
- List the two types of waves
- Identify the meaning of longitudinal wave
- Identify the meaning of transverse wave
- Label parts of longitudinal and transverse waves
- Explain how a mechanical wave is formed
- Model and compare longitudinal and transverse waves
Vocabulary
- Longitudinal wave
- Transverse wave
- Compression
- Rarefaction
- Crest
- Trough
Types of Mechanical Waves
- Mechanical waves are produced when a source of energy causes a medium to vibrate
- Transverse wave: particles move perpendicular to the wave direction (water wave, spring wave)
- Longitudinal wave: particles move parallel to the wave direction (sound wave)
Parts of Transverse Waves
- Crest: the highest point of the wave
- Trough: the lowest point of the wave
- Amplitude: the distance from the rest position to the crest or trough
- Wavelength: the distance between two consecutive crests or troughs
Parts of Longitudinal Waves
- Compression: where coils are close together
- Rarefaction: where coils are spread out
- Amplitude: the distance from the rest position to a compression or rarefaction
- Wavelength: the distance between two consecutive compressions or rarefaction
Think Pair Share - Check Your Understanding
- Draw the parts of the two types of waves learned.
Independent Activity - Practice Labeling
- Label a diagram of longitudinal and transverse waves
Group Work (Explore) - Modeling Two Types of Waves
- Use a slinky to create different types of waves
- Focus on how the slinky moves and which direction the movement is
Check Your Understanding - Do This After the Activity
- Compare and contrast longitudinal and transverse waves
- Give an example of a longitudinal and a transverse wave
- Identify which part of a longitudinal wave corresponds with crest/trough of a transverse wave
- Draw a longitudinal and transverse wave
