Doppler effect?

  1. Jan 10, 2010 #1
    This may be a dumb question , lets say there are a bunch of people on the dark side of the earth , these humans are emitting infrared photons and i am traveling by on a rocket ship
    if I travel fast enough will I see these humans glowing or emitting visible light .

    Yes. But you had better make sure that you keep the earth between you and the sun in that case because the sun would be emitting hard gamma radiation. Also, the direction matters, if you were going away from the earth the radiation would be blueshifted down into the RF.

    ok thanks for your answer , so the gamma radiation from the sun if i was going that fast would really mess me up.
