Sample Question 1
Describe the nature of standing (stationary waves).

Standing waves are created by the collision of two waves with different speeds and amplitudes.

Standing waves are formed when a wave passes through a medium without any reflection or interference.

Standing waves have varying wavelengths and directions of propagation.

A standing wave is the product of the propagation of 1 wave against a wall and its reflected wave with the same speed, same wavelength, same amplitude, opposite direction. Because the wave is reflected, the energy that is propagated returns to the same point of origin. Velocity=displacement / time, and since there is no displacement, the wave has no velocity. As well, we say that no energy is propagated

Sample Question 2
Explain the formation of one-dimensional standing waves.

Standing waves can only occur in two or three-dimensional space, not in one-dimensional space.

One-dimensional standing waves are formed by the interference of only destructive waves from a source.

Standing waves are formed when two waves moving in the same direction collide and cancel each other out completely.

As one wave is propagated at a certain fundamental frequency by the vibration of a source and at point B, it hits point A and is reflected back to point B at ? out of phase (i.e. as a particle on the forward wave reaches its amplitude, a particle in the same position on the reflected wave is half way to its amplitude) forming a standing wave with a greater amplitude
