Question

Need the right answer The speed of a wave in shallow water is a function only of the wave period. The water level at the node of a pure standing wave (R = 1) never changes, and the water velocity at all depths at that location is zero. Wave amplitude varies faster with a change in width than with a change in depth. The potential and kinetic energy components of a wave are always equal at any discrete location within the wave. Refraction, or turning of a wave, occurs because of varying wave speeds perpendicular to the direction of wave propagation. In determining the kinetic energy of a wave under the assumptions of linear theory, we ignore the kinetic energy associated with water mass above the still water level. Energy in a wave always moves at the same speed as a wave crest. Energy flux in a wave can be represented with units of Watts/m^2. A change in water depth affects the height of a propagating wave through two distinct mechanisms: refraction and shoaling. A wave generated near the coast will be presented from propagating into deep water if the angle of propagation relative to bathymetric contours is sufficiently small

Explanation / Answer

1) speed is also a function of wavelength also

so it is TRUE

2) amplitude is zero and not the velocity

So FALSE

3) since amplitude is a function of width and depth

it is true

4) KE is ame with PE at some positions only

False

5) True

6) because in still water ,waves does not produce

TRUE

7) crest is association with wave,but trnasportation is not same

False

8) Energy flux = Power/surface area = W/m^2

9) TRUE

10) True
