- 1Wave speed: C= fλ where: f= frequency λ= wavelenthVariation:
f= C/λ
λ= C/f - 2Period T= 1/f where: f= frequencyVariation:
f= 1 x T - 3Intensity: I=P/4πr^2 Where: P= power r= radiusVariation:
P= I x 4πr^2
r= √ IP/4π - 4Longitudinal WaveTransverse Waves
- 5Average human hearing: between 20Hz and 20KHz< 20Hz Infra-sounds
>20Hz Ultra-sounds - 6Polarisation...
- 7standing waves: when two waves moving in different directions match up their amplitude is added together.
- 8Fundamental Frequency: Ff= 1/2L x √T/μ Where L= length (of string) T= Tension μ=mass per unit of string1) L= λ/4
2) L= 3/4 λ
