Light & Energy | Answers |
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. |
