Question

Which of the following statements is/are true about the physical characteristics of waves? a. wave height is the vertical distance from crest to trough.b. wave steepness is equal to wave height divided by wavelength.c. if the wave steepness ever exceeds a 1 to 7 ratio, then the wave breaks.d. the depth at which orbital motion ceases is called the still water level.

Answer 1

Answer:

Option A, B, C

Explanation:

A wave’s highest part is called crest and the lowest part is called trough. The vertical length between the highest and lowest part of wave i.e crest and trough is called wave height. Hence option A is correct. Steepness of waves is defined as the ratio of height of wave to its length i.e wavelength. Hence option b is correct

And the steepness of wave should never exceed the ratio of $\frac{1}{7}$ , if ration exceeds $\frac{1}{7}$  the wave gets steep and finally breaks down

 

Hence, Option A, B, C  are correct

Answer 2

Answer: Option A,B and C.

Explanation:

A wave is a physical phenomenon that is described as disturbance of one or more field that travels through a medium, transporting energy from a location to the other without transporting matter.

Wave height is the vertical distance from crest to trough.

Wave steepness=wave height ÷ wave length.

If a wave steepness ever exceeds a 1 to 7 ratio, the wave breaks
