Along wave travels in 20m depth of water. if the amplitude of this wave in 20m depth water is 1.1 m , what is the amplitude of the same wave in 6.2 m depth? assume the wave is traveling perpendicular to the coast.

A  = 3.55 m

Explanation:

given,

depth of water = 20 m                

Amplitude of wave at 20 m depth = 1.1 m        

Amplitude at the depth  of 6.2 m              

amplitude is inversely proportional to depth of water

so,                                      

A  = 3.55 m

hence, the amplitude of the wave at the depth of 6.2 m is 3.55 m.
