hehe... sound waves?
sb ni sir, sound waves can be classified into three, audible waves, infrasonic waves and ultrasonic waves...
audible waves has a normal range of sound wave which is from 20Hz to 20000Hz...
if it is below audible range it is called infrasonic wave..
ultarasonic naman poh kpag above the audible range...
formula for liquids:
v= sqrt of B/P
^B is the bulk modulus of the liquid
^P is the density of the liquid.
formula for solid:
v= sqrt of Y/P
^Y is the Young's modulus material
^P is the density of material
Sound of Speed in General formula:
v= sqrt of elastic property / inertial property *the same as the formula for liquid and solid
formula for gas:
v= (331 m/s) * sqrt of T/273 K
^331 m/s is the speed of the sound at 0 degree celsius
^T is the absolute temperature
nice day... n22to dn! hehe... (kya cnpag mgpost)
