What is the phase diffrence between the particle 1 and 2 located as shown in

What is the phase difference between particles being on either side of a node?

The phase difference between particle velocity and wave velocity is

Two tunnels - T_(1) " and " T_(2) are dug across the earth as shown in figure. One end of the two tunnels have a common meeting point on the surface of the earth. Two particles P_(1) " and " P_(2) are oscillating from one end to the other end of the tunnels. At some instant particles are at mid point of their tunnels as shown in figure. Then - (a) Write phase difference between the particle P_(1) " and " P_(2) . Can the two particles ever meet? (b) Write the ratio of maximum velocity of particle P_(1) " and " P_(2) .

There is no phase difference between the particles within a loop of a stationary wave .

The maximum particle velocity is 3 times the wave velocity of a progressive wave. If the amplitude of the particle is 'A', then the phase difference between the two particles separation by a dsitance of 'x' is

Two particles of a medium are vibrating due to a wave propagating through the medium. If the phase difference between these particles is (pi)/(3) and distance between the particles is 10 cm then calculate the wavelength of wave.
