Support Although it is not the best illustration for the Doppler theory, it is very good for showing the interference, the result of the Doppler effect. This proves how difficult category and scope selection can be. --Foroa (talk) 06:48, 22 October 2008 (UTC)[reply]
Wrong, Doppler= relative speeds (2) - but I will not discuss that here. (speed on the left side = medium speed + object speed, on the right side = medium speed - object speed) --Foroa (talk) 12:21, 22 October 2008 (UTC)[reply]
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 It shows that with a moving object, the frequency of whatever the waves (sound, light, ect) are higher in front of the object and lower behind the object. Is the problem that it doesn't show clearly enough that it is a moving object? Pbroks13 (talk) 07:47, 24 October 2008 (UTC)[reply]
