Light and Energy

Light & EnergyAnswers
Visible Light Form of Electomagnetic Energy
Electromagnetic Spectrum Wave Lengths
Non - Visble Light - Low Energy wave lengths on the electromagnetic Specturm Low on the electomagnetic Spectrum - Radio Waves, Microwaves, Infared Radiation
High energy wave lengths on the electomagentic Spectrum X- Rays, Gamma Rays, Ultraviled Radiation
White Light (Prism) Rainbow Colors
Visible Light Can be redirected or bent
2 Major forms of bending Light Reflection(mirror) & Refraction (spoon in Water_
Reflection Properties Predictable > Bounces off
Refracation Properties Unpredictable - Angle of which is is refracted ----> Travels in same direction, optical illusion the light waves are bent so the spoon in the water handle coming out looks bent
Sound Waves disruption of medium in an organized pattern
Longer Sound Wave Lower Tones
Shorter sound wave Higher tones
amplitude (height) of the sound wave Correlates volume of the sound
Sound Waves Bounce (reflect) off of solid objects
Speed of sound changes Depending on the medium through which it travels. Closed window vs. open window (changes the wave, thus the sound)
Dopler Effect Both Light & Sound
Wave Basically a compression or expansion
Shorter (towards) wave lengths Color Blue
Longer (away) wave lengths color Red
Sound waves (toward) Louder (Siren) Waves Compressing
Sound Waves (Away) Lower (Siren) Waves Lengthening
Two (2)Difffernce between Light And Sound Speed & Medium
Light (speed) Constant and Consistant
Sound (speed) Different and varying
Light Medium No Medium Needed (Stars through Space to be seen on Earth)
Sound Medium Medium Required (Sound cannot travel through space) needs molecules. In other words talking underwater with dense molecules does not sound like talking above the water.
