    Understanding the Doppler Effect with Moving Sources and Observers

    Honestly I'm not following what you're suggesting... :-/ I got the squares simply by taking each individual formula and multiplying them together.. It then becomes clear that you get the proper term in parentheses (1+vocoso/c)/(1-vscoss/c) but the fo and fs are squared as a result of that as...

    Understanding the Doppler Effect with Moving Sources and Observers

    what youre alluding to isn't really what I'm getting at since swapping fo and fs wouldn't solve it either. The math is clearly right - I'm just confused as to how you can simplify fo^2=fs^2 *((1+(vo/c)*cos(theta_o)))/((1-(vs/c)*cos(theta_s)))

    Understanding the Doppler Effect with Moving Sources and Observers

    well of course either times (1+(vo/c)*cos(theta_o)) or divided by (1-(vs/c)*cos(theta_s)) I just can't comprehend how the product of the two shifts leads to the real equation..

    A From how far away is radiated energy of photons effective?

    I'm faced with a problem here and would really appreciate anyone's help. The question is paraphrased as follows: The eye can respond to single photons but there are certain requirements from the eye: it must receive at least 100 photons/s to process it. Assume the eye to have an area of 4E-6...

    Understanding the Doppler Effect with Moving Sources and Observers

    Homework Statement Can't figure how to prove when both source and observer are moving that the observed frequency is the product of the two independent cases below.. Homework Equations We know individual cases when source is moving and observer is still, the observed frequency is equal to...
