A shock wave is produced which passes, in two hours, through the outer layers of the star causing fusion reactions to occur. These form the heavy elements.
The shock wave forms a cone of pressurized air. A sharp release of pressure after the buildup of a shock wave is heard as a sonic boom. It is similar to the sharp release of pressure when a pin pops a balloon and makes a loud noise.
Continuous Wave (CW) transmission is when there is an electromagnetic carrier wave present and the message signal, be it voice, video or data, is impressed upon the carrier by modulating its amplitude, phase or frequency.
Sensing the wave front requires a bright source, a laser beam, a bright star, a planet, or an asteroid.

If light is a wave phenomenon, then a medium is required. Sound waves travel through the air but not through a vacuum; ripples require a watery medium. At first it was thought that air would be the medium that would support the propagation of light.
Interference, Wave: A wave is something that moves along and has high points (crests) and low points (troughs).
damped wave Any wave whose amplitude decreases with time or whose total energy decreases by transfer to other portions of the wave spectrum. damping The suppression of oscillations or disturbances; the dissipation of energy with time.
The mostly accepted theory of the spiral arms is the density wave theory. It says that the stars indeed rotate at different speed, but the density of the interstellar medium form a wave.
Seyfert galaxies. A kind of so-called 'active' galaxy. Seyfert galaxies have fairly small but bright nuclei and weak spiral arms. These galaxies are also strong emitters of radio wave energy.

But light also exhibits the characteristics of a wave. Traditionally, wave activity is explained by imagining a pebble being dropped into a lake, but that imaginary lake has been filled with imaginary pebbles years ago.
Since Jansky's original work was done at 20 MHz (about 15 metre wave length) and a beam width of about 25 degrees, Reber wanted to narrow the effective beam width to obtain finer detail.
