Can electromagnetic waves travel through a medium?
2. If YES - how..  give two examples]]> 2018-06-11 05:18:33 UTC https://padlet.com/rajeswari_meganathan/e1kwcpjzkl3z/wish/266536333 1. arunfreekzz1 https://padlet.com/rajeswari_meganathan/e1kwcpjzkl3z/wish/266559766 electromagnetic waves which can travel through vacuum of outer space. electromagnetic wave require the presence of medium in order to transport their energy from the location]]> 2018-06-11 08:31:24 UTC https://padlet.com/rajeswari_meganathan/e1kwcpjzkl3z/wish/266559766 MansurAli mansurdsmiley787 https://padlet.com/rajeswari_meganathan/e1kwcpjzkl3z/wish/266559825 1.

examples:
radio waves,microwaves,infrared waves,uv rays,x-rays,gamma rays.

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves ca travel not only through air and solid materials, but also through the vacuum of space. 
2. FOR EXAMPLE:-
              * When a balloon is rubbed against a head of hair, astatic electric charge is created causing their individual hairs to repel one another. ]]> 2018-06-11 08:34:47 UTC https://padlet.com/rajeswari_meganathan/e1kwcpjzkl3z/wish/266560265 ELECTROMAGNETIC WAVES vinithkumarsri26 https://padlet.com/rajeswari_meganathan/e1kwcpjzkl3z/wish/266560440 Electromagnetic waves  are waves which can travel through the vacuum of outer space.Mechanical         waves, Unlike electromagnetic wave,require the presence of a material medium in order to transport their energy from one location to another....... electromagnetic  waves are created  by the vibration of an electric charge

There was a time where people believed that you needed a medium, which made many think there was some sort of medium in space called the aravindgokul19 https://padlet.com/rajeswari_meganathan/e1kwcpjzkl3z/wish/266563140 2018-06-11 08:51:04 UTC https://padlet.com/rajeswari_meganathan/e1kwcpjzkl3z/wish/266563140
