Electromagnetic radiation is a natural phenomenon that moves as a wave.

Electromagnetic Radiation. Electromagnetic radiation is a natural phenomenon that moves as a wave. An electromagnetic wave is a set of two transverse waves that move perpendicular to each other: One wave is an electric field The other wave is a magnetic field

So much to remember, so little space

So much to remember, so little space. Diffraction Limits on Light. What have we learned?. Any traveling sinusoidal wave may be described by y = y m sin( kx ? w t + f ) Light always reflects with an angle of reflection equal to the angle of incidence (angles are measured to the normal).

Lasers (Light Amplification by Stimulated Emission of Radiation)

Lasers (Light Amplification by Stimulated Emission of Radiation). A laser is a device that can produce a very narrow intense beam of monochromatic coherent light. The emitted beam is nearly perfect plane wave. Common Laser System. Stimulated Emission (1). It is pointed out by Einstein that:
