Rays and Wave Fronts
Light, Sound and ripples on the water surface are ell examples if waves.
A continuous wave involves a succession of individual oscillations. A wave pulse involves just one oscillation. All waves can be classified as longitudinal or transverse. Examples are: They all transfer energy from place to place They do this without net motion of the medium through which they travel They all involve oscillations or vibrations of one sort or another
Wave and Type Example of Energy Transfer Sound Waves - Longitudinal When the sound waves hit a surface they make it vibrate Wave Ripples - Transverse A floating Object Gains Gravitational Potential Energy as it Moves up and Kinetic Energy as it Moves Light Waves - Transverse Light waves are in the Form of photons which carry energy Earthquake P Waves - Longitudinal P waves compress and expand the Earths s interior Earthquake S Waves - Transverse S waves move the Earths surface move up and down Waves on a Stretched String - Transverse Waves on a string produce sound waves when the string vibrates Compression Waves on a Stretched Spring - Longitudinal Compressions pass along the spring when one end is jerked Add comment
