Explain Centripetal force??
Sir Isaac Newton suggested that motion in a straight line is most natural, and that deviations from this type of motion are caused by a force pulling the body absent of line. When the force acts on the body from a fixed point, like a body moves in a circle, and the force towards the centre is known as a centripetal force.
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
