• Requires a Medium

• Cannot travel in a Vacuum

• Speed: Gas < Liquid < Solid

AMPLITUDE & LOUDNESS

FREQUENCY & PITCH

Some Important Formulae:

•  $f=\frac{1}{T}$  

•  $f=\frac{No\ of\ Oscillations}{Time\ Taken}$  

•  $T=\frac{1}{f}$  

•  $T=\frac{Time\ Taken}{No\ of\ Oscillations}$  

SOME HIGHER ORDER THINKING SKILLS

"The important thing is not to stop questioning" - The guy who found :

 $e=mc^2$
