Homework Help: Doppler Effect on light question

  1. Aug 2, 2005 #1
    In "Concepts of modern physics 6/e by arthur beiser", there's a paragraph on pg11 explaining th effec on the observer moving perpendicular to a line between him and the light source. Why is the proper time between ticks to=1/vo?

    you mean v observer / v source = sqrt((1+b)/(1-b))

    where b = v / c and v source = c / lambda source
