in coherent light, check your science book
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
they are asorbed.
Is the direction of the wave of the light energy in the same path of the photon.
Light waves with the same phase and frequency are said to be coherent.
Heirich Hertz. Maxwell theorized that light and electricity were the same based on the speed of electric waves and light waves. Hertz actually created the electromagnetic waves and demonstrated their light like behavior. This demonstration confirmed Maxwell's prediction.
It's polarized light
unpolarized light = light waves vibrate in more than one plane Polarized light = vibrations of light waves occur in a single plane.
Cause rock particles to vibrate in same direction that waves travel
Longitudinal waves
longitudinal waves
Plane waves travel parallel to each other in the same plane hence the name.
secondary waves
Primary waves.
