What is Attenuation?
Attenuation:
Attenuation is a reduction within the amplitude and intensity of a signal. This is a significant property into optical communications. This is a natural effect of signal transmission over long distances. This is sometimes termed as 'loss'. Loss or Attenuation in fibre is measured into units of decibels per unit length of medium (dB/ km).
In a young's double slit experiment a point on the screen is similar distance from both the slits if any one of the slit is closed the intensity at P due to the other slit is 0.02
Explain Thermal Physics and Quanmtum mechanics Thermal Physics , in which one studies the nature of heat and the changes that the addition of heat brings about in matter.
