Review (criteria)	Oppose None of them is good enough to honour the saying: "a picture is worth 1000 thousand word". In bothncases, we must know what Doppler effect is to understand the picture. -- Alvesgaspar (talk) 19:28, 22 October 2008 (UTC)[reply] Comment the description on the image page is part of the value of a VI candidate. --Eusebius (talk) 19:53, 22 October 2008 (UTC)[reply] Comment - Maybe it isn't easy but I'm convinced it is possible to make a less abstract depiction. Like the classic one with a train moving and whistling, and two observers (one in each side) listening to two different frequencies. -- Alvesgaspar (talk) 23:04, 22 October 2008 (UTC)[reply] Comment - here is a very crude sketch just to explain my idea. Should the "waves" leaving the whistle be symmetrical or not? Well, it depends on the reference frame we consider. -- Alvesgaspar (talk) 23:26, 22 October 2008 (UTC)[reply] Support This drawing is better to explain the Doppler effect on a single axis (the other image is in two). --Foroa (talk) 08:54, 29 October 2008 (UTC)[reply] Scores: 1.
