Figure. Represents the displacement `y` versus distance `x` along the direction of propagation of a longitudinal wave. The pressure is maximum at position marked

A wave front is represented by the plane y=5-x Find the direction of propagation of wave.

If E and B represent electric and magnetic field vectors of the electromagnetic wave, the direction of propagation of eletromagnetic wave is along.

The same progressive wave is represented by two graphs I and II . Graph I shows how the displacement 'y' varies with the distance x along the wave at a given time. Graph I shows how y varies with time t at a given point on the wave. The ratio of measurements AB to CD , marked on the curves, represents :

An electromagnetic wave is propagating along Y-axis. Then

The same progressive wave is represented by two graphs I and II. Graph I shows how the displacement y varies with the distance x along the wave at a given time. Graph II shows how y varies with time t at a given point on the wave. The ratio of measurements AB to CD, marked on the curves represents:

With the propagation of a longitudinal wave through a material medium, the quantities transmitted in the propagation direction are

The figure gives the displacement versus time graph of a simple harmonic oscillator. The position with maximum speed directed down wards is at

If vec(E) and vec(B) represent electric and magnetic field vectors of the electromagnetic wave, the direction of propagation of electromagnetic wave is along
