The ripples spreading out below the pulsar like waves on a lake show where streams of electrons and positrons, shooting away from the pulsar at nearly the speed of light, begin to bunch up along the pulsar's changing magnetic field.

Instead of relying on light waves emitted by electrons, it would use radiation emitted when the nucleus is excited to a high energy state, and then drops into a lower energy state.

Plasmons are coordinated waves, or ripples, of electrons that exist on the surfaces of metals at the point where the metal meets the air.

Among other achievements, his group has used the response of electrons to measure the electric field of a laser's ultrashort pulses and display the waveform, much like displaying a radio - frequency wave on an oscilloscope.

Their breakthrough sensor technology is based on a curious phenomenon: a quasiparticle that emerges when light waves couple with the electrons» oscillations of certain solid surfaces.

Counterclockwise polarized light, on the other hand, produces a minimal amount of blue light because the polarization tends to push the electrons outward so that the waves from all around the nano - spiral interfere destructively.

In the case of electrons on helium, the system is pure and homogenous, but the surface of liquid helium is nonetheless disturbed by capillary waves — ripples associated with the surface tension and similar to small, circular ripples in a pond when a pebble is tossed into the water.
