Properties of waves
-
For any wave, its wavelength is the distance from a point on the wave to the equivalent point on the next wave e.g. from one wave through to the next
For any wave, its frequency is the number of waves passing a point per second.
-
For any waves, its amplitude is the maximum displacement of a point on the wave from its undistributed position, such as the height of the wave crest (or the depth of the wave trough) from the position at rest
Nature of waves
Longitude waves oscillate parallel to the direction of energy transfer of the waves. Sound waves in are a longitude waves
-
Transverse waves oscillate perpendicular to the direction of energy transfer of the waves, ripples on the surface of water are transverse waves. So are all electromagnetic waves
-
More about waves
-
To investigate waves use; a ripple tank for water, a stretched string for waves in a solid, a signal generator and loudspeaker for sound waves
