Electromagnetic 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.]]> 2017-02-27 15:57:28 UTC https://padlet.com/dayi05789/ul3g0c6366sr/wish/156453738 dayi05789 https://padlet.com/dayi05789/ul3g0c6366sr/wish/156457767 a transverse wave is a wave vibrating at right angles to the direction if its propagation. A wave propagation is any of the ways in which waves travel. with respect to the direction of the oscillation relative to direction of the propagation, we can tell apart longitude waves and transverse waves. Transverse waves are a form of a mechanical wave. In a transverse wave, the medium has particles that vibrate in a direction perpendicular to the direction of the propagation wave. these waves can propagate through solids and liquids but not through gases, because gases don't have elastic properties. ]]> 2017-02-27 16:06:33 UTC https://padlet.com/dayi05789/ul3g0c6366sr/wish/156457767 dayi05789 https://padlet.com/dayi05789/ul3g0c6366sr/wish/156460767

Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves. Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component. An electromagnetic wave transports its energy through a vacuum at a speed of 3.00 x 108 m/s. The propagation of an electromagnetic wave through a material medium occurs at a net speed which is less than 3.00 x 108 m/s. ]]> 2017-02-28 21:51:02 UTC https://padlet.com/dayi05789/ul3g0c6366sr/wish/156878975
