The first waves to arrive at a seismograph station are primary waves, or P waves.
lag time=(time it takes the s-wave to travel)-(time it takes the p-wave to travel)
The answer is right there in the words of the question. Radio and light are the same physical phenomenon, and they travel at the same speed. The star is 5 light years away. That means the distance that light ... and radio ... travel in five years. It takes light from the star 5 years to reach us, and it takes radio from us 5 years to reach the star.

To estimate the speed of a wave, a person can estimate the distance the wave is from shore and then time how long the wave takes to reach the shore. For example, if a wave is one mile out and it takes one minute to reach shore, the wave is traveling at 60 miles per hour.
wave a
That would be a secondary, or 'S' wave. Moving in a snakelike movement, this wave has to travel a farther distance, so it takes longer to reach the recording equipment.
Siadar Wave Power Station was created in 2011.
if you survive in lone wolf long enough you can save reach but as every wave gets harder it is almost inpossible
it is picking up of the short wave station at two nearby points on the receiver or When a receiver picks up the same short wave station at two nearby points on the receiver dial the double spotting phenomenon takes place
it takes up to 100 years
