when we play a guitar the sound from its string vibrates and sound passes in the air molecules and it ends in the started position.

in water
in a calm watery pool when we throw a twig it vibrates and pass the energy passes and the water molecules starts moving and ends at the starting position.

in electromagnetic waves
the energy is transferred through electric radiations and magnetic field.any waves can pass energy but cannot pass mass. ]]> 2018-06-18 08:33:25 UTC https://padlet.com/rajeswari_meganathan/v7sgigq3wtcb/wish/267583164 Water waves are formed by vibrations in a liquid and sound waves are formed by vibrations in a gas (air). ... Sound waves cannot travel in the vacuum of space because there is no medium to transmit these mechanical waves. Classical waves transfer energy without transporting matter through the medium. arunfreekzz1 https://padlet.com/rajeswari_meganathan/v7sgigq3wtcb/wish/267583935
ectromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another.

  •  Earth Quake Waves 
    •  Earth has few layers and one of them is the lithosphere. It is broken down to tectonic plates and sometimes these plates slide inside the earth.

Some energy waves need a medium, such as water or air, through which to travel. The medium moves back and forth as waves carry energy through it, but it does not actually travel along with the waves]]> 2018-06-18 08:51:02 UTC https://padlet.com/rajeswari_meganathan/v7sgigq3wtcb/wish/267586180 athleticanand7 https://padlet.com/rajeswari_meganathan/v7sgigq3wtcb/wish/267586740 2018-06-18 08:54:21 UTC https://padlet.com/rajeswari_meganathan/v7sgigq3wtcb/wish/267586740
