Q1 Is it possible to have a standing wave if the amplitude of two component waves are not equal???????
Q2 In a standing wave,is the energy density ZERO at nodes???
Q3 Is there any relationship between wave speed and maximum particle speed????

3) no i think they r independent..
y=Asin(kx-wt)
particle velocity maximum=Aw
wave velocity=wavelength*w/2 pi

Q.3. yes there is a relation between wave velocity and particle velocity:
dy/dt= -v*dy/dx
where dy/dx is the slope at the particle, v is the wave velocity, dy/dt is the particle velocity.
dy/dx represents the partial differentiation of y w.r.t. x keeping t constant, and same is for dy/dt (w.r.t. t keeping x constant)
Plz rate

YES THINK ABT THE STANDING WAVES HAVING FREE END YOU HAVE REFLECTED WAVES HAVING AMPLITUDE 2X .............................NOT SO GOOD Q.

Q.2. in the satnding wave there is no transmission of energy. Hence the energy between two consecutive nodes will be constant. THE ENERGY DENSITY AT NODES IS ZERO

Q.1. Actually a standing wave is produced by the superposition of the original wave and its reflection. Hence their amplitude is same.
