The refractive index is a term used to measure how light or radiation propagates through a medium. In plasma, it is considered for the filamentation process, where filamentation focuses on high power laser pulse. Calculate the plasma refractive index based on the given values.
Formula
η = [1-(vp/v2)]1/2
Where,
η = Plasma Refractive Index
vp = Plasma Frequency
v = Frequency
