![]() The vibration of the wave is confined within the string, amplifying the sound as the nodes overlap. The points of reflection on the string are the two ends. Microwaves trapped inside a microwave oven have this feature, producing antinodes of intense heating and nodes where no energy is transmitted into the food this is the reason that microwave ovens have rotating platforms to make heating of the food item more uniform.Ī violin string will be seen to have discrete, stable regions of motion and lack of motion, the requirements of the standing wave phenomenon. If the waves were confined in a harbor so that they could amplify, it might be possible to produce a standing wave. Light with a specific wavelength has no "resonant" character, and neither do waves striking a pier. In other words, resonance must occur, and that usually suggests confinement of the wave in some fashion.Ī fan and a bus make noise and vibration, but the sound does not resonate. A simple definition of a standing wave is a wave that is self-reinforcing, which is to say that reflection of the wave through the medium results in some areas of amplification (anti-nodes) of the wave and some areas of nullification (nodes).
