Product description
Pulsed radiation from the pulsar CP1919 + 21 at a frequency n1 = 80 MHz reaches the Earth Dt = 7 s later than the corresponding pulse at a frequency n2 = 2000 MHz. Estimate the distance L to the pulsar if we take the average electron density in interstellar space to be N ~ 0.05 cm-3.
