Wave velocity is the velocity of oscillation of particles of medium.

Explain the types of waves on the basis of direction of oscillations of particles of medium.

Assertion: Average speed of a particle in a given time interval is never less than the magnitude of the average velocity. Reason: The magnitude of the velocity (instantaneous velocity) of a particle is equal to its speed.

Give the direction of velocity of SHM particle.

What is the phase difference the velocity and acceleration of a particle executing SHM?

Amplitude of a harmonic oscillator is A , when velocity of particle is half of maximum velocity, then determine posiition of particle.

According to particle theory of light what is the velocity of light in a dense medium, compared to that in rare medium ?

The plot of velocity (v) versus displacement (x) of a particle executing simple harmonic motion is shown in figure. The time period of oscillation of particle is :-

Statement-I : When velocity of a particle is zero then acceleration of particle is zero. Statement-II : Acceleration is equal to rate of change of velocity.

A travelling harmonic wave on a string is described by y(x,t) = 7.5 sin (0.005 x + 12t+ pi//4) (a) what are the displacement and velocity of oscillation of a point at x=1 cm, and t=1s? Is this velocity equal to the velocity of wave propagation? (b) Locate the points of the string which have the same transverse displacements and velocity as the x=1 cm point at t=2s, 5s and 11s
