Question

define tidal and wave energy​

Answer 1

Tidal power or tidal energy is a form of hydropower that converts the energy obtained from tides into useful forms of power, mainly electricity.

Wave energy (or wave power) is the transport and capture of energy by ocean surface waves. The energy captured is then used for all different kinds of useful work, including electricity generation, water desalination, and pumping of water. Wave energy is also a type of renewable energy and is the largest estimated global resource form of ocean energy.

Answer 2

$\huge\bold\red{Tidal\: Energy:-}$
$<I>$The rise of the sea water due to the gravitational pull of the moon is called a high tide where are the fall of the sea water is called a low tide the tidal waves in the sea build up with the receipt of twice a day the anonymous movement of the water between the high tides and low tides provide a very large sources of energy in the coastal areas of the world the tidal energy can be hardness to the by construction at idlebrain are the tidal dam across a narrow opening to the sea .

$\huge\bold\orange{Wave\: Energy:-}$
$<i><b>$ Wave energy here means sea waves energy energy from the sea is also available in the form of the sea wave due to the blowing of the wind on the surface surface of see very fast see which moves on its surface due to their highest speed sea waves have a lot of kinetic energy in the energy of moving sea waves can be used to generate electricity a wide variety of the devices have been developed to trap sea wave energy to turn turbines and derive generators for the production of the electricity .

i)one idea is to setup floating generators in the sea they would have to move up and down with the sea waves the movement of word drive The generated to produce electricity .

ii) another idea is to let the sea waves move up to the down inside glass tubes is the wave moves up there in the tubes kiss compress the compressed air can be used to turn a turbine of a generator to produce electricity .
