The difference between sound and light They’re both waves, after all
Speed Sound slow : about 330 m/s in air Light fast : about 300,000,000 m/s in air
Spectrum You hear most of the vibrations that are out there. You see only a small fraction of the electromagnetic waves present
Medium Sound waves travel in something Light can travel in a vacuum Different frequencies of light can travel right through dense materials (x-ray through bone)
Sound waves & Light waves Reflect Refract Diffract Interfere
Light is tied into the time and space in the Universe in a way that requires Einstein & Relativity to understand Because, no matter what the speed of light is in a vacuum or a material, nothing can go faster. Nothing. NOTHING.
Chapter 1: Waves Review PowerPoint. Amplitude is a measure of what in a wave? Amplitude measures the amount of energy in a wave.
WAVES REVIEW & ELECTROMAGNETIC WAVES INTRODUCTION Radio Waves Microwaves Infrared Visible Light (Red, Orange, Yellow, Green, Blue, Indigo & Violet) Ultraviolet.
Chapter 10. Nature of Waves Wave Repeating disturbance or movement Carries energy through matter and space.
A difficult question, thousands of years in understanding. Very difficult to study, since it cannot be caught, and it is very difficult to measure.

Waves. A wave is a disturbance that carries energy through matter or space. It does not move matter. Energy may spread out as a wave travels.
Unit 7: Waves, Sound, and Light... SPS9: Properties of Waves Amplitude: the height of the wave, measured in meters. Wavelength: the distance between adjacent.

WAVES Wave motion allows a transfer of energy without a transfer of matter.
WAVES Definition: A traveling disturbance that carries energy through matter and space Waves transfer energy without transferring matter. Waves are produced.
Waves can also be reflective and refractive Waves can bounce off of something after striking it. That is a reflection. Sound and light waves can equally.
Characteristics of Waves Chapter 9 S8P4a. Identify the characteristics of electromagnetic and mechanical waves. S8P4d. Describe how the behavior of waves.
The Electromagnetic Spectrum Coach Smith. EM Spectrum 0 Types 0 Radio 0 Microwave 0 Infrared 0 Visible light 0 Ultraviolet 0 X-rays 0 Gamma rays.

Chapter 14 Light and Color. Genesis 1: 3-4 God said, “Let there be light”; and there was light. And God saw that the light was good: and God divided the.
Light is an electromagnetic wave. Visible light is only a small section of the electromagnetic spectrum. The electromagnetic spectrum stretches from radio.
Waves, Sound, and EM Waves. Sound Example of compressional wave Can travel through any type of matter Speed of sound depends on the substance the medium.
Chapter 11 Waves. wave – a rhythmic disturbance or movement that transfers energy through matter or space – examples: ocean waves disturb the water and.
Wave Basics – Day 1. Fill in the blank: Waves transmit ________. energy.
Light is Energy The term “Light” can describe many different forms of electromagnetic energy.
Energy an object is said to have “energy” if the object has the ability to change its environment Two ways to transfer energy 1. through the application.
Waves S8P4: Students will explore the wave nature of sound and electromagnetic radiation.
Sound Waves You Have to Hear This!!!! Producing a Sound Wave Like all waves, sound waves are produced by a vibration. A tuning fork vibrates to produce.
A mechanical wave is a rhythmic disturbance that carries energy through matter and space. All mechanical waves are made by something that vibrates.
Radiant Energy or Electromagnetic Energy (EM) All radiant energy travels at 3.0 x 10 8 m/sec in space Velocity of a wave = wavelength x frequency Visible.
Reflection of Light Definition of Reflection Types of Reflection Laws of Reflection Plane Mirrors Uses of Reflection.
Waves and Wave Interactions Chapter Physical Science.
Physics Review Day 3. Waves A wave is a repetitive motion that transfers energy through matter or space There are two types of waves: –Transverse –Longitudinal.
Chapter 22 Objectives Describe reflection, refraction, diffraction, and interference. Compare destructive interference with constructive interference.
Waves and the Electromagnetic Spectrum 8 th grade.

Waves 7 th Grade Science. Types of Waves Electromagnetic Waves: Do not require a medium to move Matter Waves: Produced by electrons and particles Mechanical:
What are Waves? Waves are an important part of the Earth, and they’re not just in the water!
WAVES Essential Questions: What is a wave? How do waves travel? What are the types of waves? What are the properties of waves? What are 4 types.
Chapter 15 - Sound Sound wave is a longitudinal wave.
Electromagnetic energy (light) is an example of a transverse wave. Electromagnetic Energy (Light):
Young’s Double Slit Experiment- models light as a wave.
A wave is a disturbance that transmits energy through matter or space.
Electromagnetic Waves. An electromagnetic wave a disturbance that transfers energy through a field. Electromagnetic waves are called EM waves There are.
Chapter 11 Waves. Chapter 11.1 Notes Wave is a disturbance that transmits energy through matter and space. Medium is the matter through which a wave travels.
Waves Vocabulary Review Properties of Waves The Electromagnetic Spectrum.
REVISION SOUND. DOPPLER EFFECT Doppler effect as the change in frequency (or pitch) of the sound detected by a listener because the sound source and the.
26 Sound What is the source of all sound? 26.1 The Origin of Sound.
