Work of Sea Waves

The motion of sea waves is

The oil is sprinkled on sea waves to calm them down. Why ?

Sea gel is

An observer standing near the sea-coast counts 48 waves per min. If the wavelength of the wave is 10 m, the velocity of the waves will be

An observer standing at the sea coast observes 54 waves reaching the coast per minute. If the wavelength of a wave is 10 m , find the wave velocity.

The speed of sound in sea water is 1530 m//s . The wavelength of a wave transmitted through the sea is 0.02 m . Find its frequency.

Find the depth of sea if longitudinal waves from a ship are sent inside sea and from the bottom of sea, the waves return back after 3s. Density of water = 10^(3) kg//m^(3) and bulk modulus of water = 1960 x 10^6 N//m^(2) .

An observer standing at the sea coast observes 54 waves reaching the coast per minute. If the wavelength of a wave is 10 m , its speed is :

Trichodesmium erythrium which imparts red colour to sea water of red sea is a :-
