Q:

What was the largest wave ever recorded?

A:

Quick Answer

As of 2014, the largest wave ever recorded was a tsunami that occurred at Lituya Bay, Alaska, according to Geology.com. The wave occurred during the night of July 9, 1958 and rose to over 1,720 feet in height.

Full Answer

The wave was created by a massive landslide that took place at the edge of a narrow bay after an earthquake. Lituya bay sits on the Fairweather fault, making earthquakes a common hazard for the area. According to Geology.com, the rockslide at the base of the bay dropped nearly 3,000 feet into the water, which was responsible for the extreme force of the wave as it traversed the entire inlet and swept away millions of trees.

  • Q:

    What is the difference between compression and rarefaction?

    A:

    Compression refers to the region of a longitudinal wave where the particles are closest to each other, while rarefaction refers to the region of a longitudinal wave where the particles are farthest apart from each other. This basic foundation of a longitudinal wave, including compression and rarefaction, differs from other waves containing crests and troughs.

    What is an incident wave?

    A:

    An incident wave emanates from a source of wave production. If there is a boundary from which this wave is reflecting, the returning wave is known as the reflected wave.

  • Q:

    What is the propagation constant?

    A:

    The propagation constant is the rate at which the amplitude of a wave diminishes as it propagates outward from its source. The practical effect of this diminution is that wave amplitude drops at a predictable rate as the wave moves along a line of transmission.
