Many Physic Principles Well Illustrated By These Experiment Designs.

A very scientific design using physic principles to illustrate potential energy, kinetic energy, lever system,electronic gadzet and etc--to produce work output. it may seem a bit absurd ,might be using a bit camera trick to cover up the effiency of the machine system. Nevertheless it is very excellent and unique, seemingly real and workable by established principles in physicsDont' miss. Check-In ==>XXXXX . Remember to come back here to the blog.

Sound, Sound Wave,correlation between pitch and color, and oscilloscope tuitorial

Water drops canon (sounds of chaos)
Transverse and Longitudinal Waves
water in slow motion
Physics: Wave Speeda synaesthetic correlation between pitch and color.
a specific color linked to a specific note pitched over several octaves across a keyboard.
loosely based on Scriabins theory that each note in the octave can be associated with a specific color. Singing Rods: Frequency and VibrationPhysics Project : WavesFrequency
The higher the frequency, the more cycles a wave would make in a second, which affects the pitch of sound. As seen when the speaker vibrates more, the pitch gets higher. (1Hz,20Hz,100Hz,1500Hz)
Amplitude
Amplitude is seen the the project as how much the beads move about. The higher the amplitude, the more the beads bounced about and the louder the sound was.
Applications
-Music Synthesis
Synthesizers make use of frequency modulation to make music (eg. A440) Using the variety of frequencies, and different wave shapes (eg. Sine, Square, Sawtooth), interesting sounds can be produce which form music.
