Here the westerly ...[Read More]

From the tiny vibrations which travel through air, allowing us to hear music, to the mighty waves which traverse oceans and the powerful oscillations which shake the ground back and forth during an earthquake, waves are an intrinsic part of the world around us. As particles vibrate repeatedly, they create an oscillation, which when accompanied by the transfer of energy, creates a wave. The way in ...[Read More]
