If a wave has a wave height of 5 meters, in what depth of water would it begin to break?

6.5 meters

Explanation:

Background Knowledge:

The most familiar example of breaking wave is the breaking of water surface waves on a coastline.

Explanation:

The process of Wave breaking in most of the cases occurs when the amplitude reaches the point that the crest of the wave actually overturns

Factors by which waves are produced:

Different type of waves are produced and varied according to different type of factors. These factors are

Wind direction

Type of swell

Sea floor features

Slope of sea bed

Direct answer of the question:

In general rule, Waves start to break on reaching a water depth of 1.3 times the wave height.

In this question wave height is 5 meters so wave breaks on

5 × 1.3 = 6.5 meters

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
