2π/k
y(x,t) = Asin(kx - ωt + φ)
What is the formula to find φ ?
φ = kx
φ = Ax
φ = kT
φ = λx
Determine the formula for velocity of wave, v
v = λ/t
v = fλ
v = tλ
v = λ/f
Progressive wave consist of 2 types, which is transverse and longitudinal.
Determine the transverse and longitudinal definition.
Particle of the medium move in a direction parallel to the direction of the wave propagation
Particle of the medium move in a direction perpendicular to the direction of the wave propagation
Particle of the medium move in a direction horizontal to the direction of the wave propagation
Particle of the medium move in a direction vertical to the direction of the wave propagation
y= Asin( ωt ± kx)
What direction does ± ensemble ?
+ ( right)
- ( left )
+ ( left )
- ( right )
Which is true about stationary waveequation ?
Same frequency, amplitude & velocity, v but travelling in opposite direction
velocity travel in the same direction , amplitude & velocity, different frequency
velocity travel in the same direction , different frequency
Which statement is true about progressive wave?
Propagate away from the source
Nodes are found
Energy transferred
The points between 2 consecutive nodes are in phase
