Question

Physics

Short pulses of microwave radiation are emitted fromthe Crab nebula at a distance
L from the earth. When they reach the earth, the frequencycomponents of the pulses
are dispersed after a travel time T, such that waves of differentfrequencies arrive at
different times. The observed dispersion is due to the interveninginterstellar plasma,
which enables us to estimate the electron density of this plasma.Assuming one knows L
by other means, obtain the expression for the electron density.Assume v p ≈ vg which is
a reasonable approximation for interstellar medium.

If we assume that the pulses emmited by the Crab Nebula travelat the speed of light theyd take some finite amount of time toreach to the Earth However theres an observed time delayaccounted by the fact that the space is not a perfect vacuum Theinterstellar environment is    See Answer
