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.

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 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.

Light is an electromagnetic wave. Visible light is only a small section of the electromagnetic spectrum. The electromagnetic spectrum stretches from radio.
