What is meant by (i) particle velocity and (ii) wave velocity. How are they related ?

The relation between the particles velocity and wave velocity is -

How does particle velocity differ from wave velocity?

What is meant by phase of a wave ?

What is meant by (i) peptide linkage (ii) biocatalysts ?

What is meant by (i) rarefaction (ii) condensation ?

A sine wave has an amplitude A and wavelength lamda . The ratio of particle velocity and the wave velocity is equal to (2piA=lamda)

In travelling waves, the relation between particle velocity V_(p) , wave velocity V wave shape slope m is given by

What is meant by relative velocity ? Write an expression for the velocity of A and B particle relative to the other moving with velocities v_ and v_ along a straight line.

What is meant by the intensity of a wave ?

S_(1) : The particles speed can never be equal to the wave speed in sine wave if the amplitude is less then wavelength divided by 2pi . S_(2) : In transverse wave of amplitude A, the maximum particle velocity is four times its wave velocity. Then, the wave length of the wave is piA S_(3) : the phase difference between two points separated by 1m in a wave of frequency 120 Hz is 90^(@) . the velocity of the wave is 480 m/s
