Scattering & Spectrum
continue studying this chapter, first we are going to explain certain
definitions and concepts necesary for understand these topics. Talking
about the light, as we had seen the light is a wave and it's velocity
is constant and equal to 3x10^8 m/s.
the light is a wave, let's talk about waves: Everybody has a basic
idea of what a wave is, but can't define it. A wave is a perturbation
an ambient (generally elastic), trough it the wave transmite itself
with certain frecuency, and wavelength. The light is an electromagnetic
wave, so it is a perturbation of electromagnetic character.
awave have 3 magnitudes: period, frecuency and wavelenght.
(T): It's the time that a wave delay for go over the length of one
wavelenght. It's unit is the second.
(l): It's the distance between two points
that are in concordant to the phase of the wave. Its unit is the
(f): It's the inverse of the period (1/T). Its unit is the hertz.
