Hi there, people of the earth!!! On this site, you will find a weird but wonderful collection of FUN Physics. Physics is often regarded as the "Dreaded Subject". The stereotypical view of a physicist is one standing by a borad filled with crazy symbols and numbers. This site are meant to show the other side of physics.....both interesting and funny. Cool!!

Hi! My beautiful name is Ellaine G. Dela Cruz. I'm one of the student of the star section, DARWIN! Yehey. Clap clap clap. By the way, I like listening to music, watching tv, surfing the net, sleeping and last but not the least, eating! Yehey. I don't like making a lot of assignments(btw, who likes it?)

A month passed by,we are now on sound wave.YEHEY. As Mr. Mendoza said, sound wave is a longitudinal wave travelling through a medium and produce by vibrating object.

Compression- high density - crest
Rarefaction- low density - trough

Categories:
1. Audible - heard by the human ear, 20 Hz to 20000 Hz
2. Infrasonic- below the audible range
3. Ultrasonic- above the audible range
Ultrasound- produce images of small objects

Speed of sound- elastic and inertial

Speed(liquid)=

Speed(solid)=

Speed(air)=331m/s times the square root of T over 273 K
T=the absolute temperature

Speed(general)= elastic property over inertuial property
