Core Idea PS4: Waves and Their Applications in Technologies for Information Transfer by Mind Map: Core Idea PS4: Waves and Their Applications in Technologies for Information Transfer

1. PS4.A: Wave Properties

1.1. All Waves Have

1.1.1. Wavelength

1.1.1.1. length

1.1.2. Amplitude

1.1.2.1. Pitch/Intensity

1.1.3. Frequency

1.1.3.1. How Often

1.1.4. Resonance

1.1.4.1. Waves add up in phase

1.2. Transfers energy without moving matter

1.3. Grade Endpoints

1.3.1. By end of grade 12

1.3.1.1. wavelength and frequency are related by speed and travel of the wave, depending on medium

1.3.2. By end of grade 8

1.3.2.1. Patterns of waves using wavelength, frequency, and amplitude

1.3.3. By end of grade 5

1.3.3.1. Waves can differ in amplitude and can add or cancel when they cross

1.3.4. By end of grade 2

1.3.4.1. Waves are regular patterns of motion

1.4. Can pass through different mediums

1.4.1. Air

1.4.2. Water

1.5. Can be used to transfer information

1.6. Types of Waves

1.6.1. Soundwaves

1.6.1.1. Made by speaking or playing music/sound

1.6.2. Waterwaves

1.6.2.1. Ripple when disturbed

2. PS4.B: Elecromagetic Radiation

2.1. Types

2.1.1. Radio

2.1.2. Microwaves

2.1.3. Light

2.2. Wave Patterns

2.2.1. Magnetic Fields

2.2.2. Particles

2.3. Grade Endpoints

2.3.1. By end of grade 12

2.3.1.1. Radiation can be molded as a wave of changing electric and magnetic fields or as particles called photons.

2.3.2. By end of grade 8

2.3.2.1. When light shines on an object, it is reflected, absorbed, or transmitted through an object. Frequency changes means change in color of the wave.

2.3.3. By end of grade 5

2.3.3.1. Light travels through space to Earth from The Sun and distant stars

2.3.4. By end of grade 2
