1. informative AND fun to watch
   in salute you , doc

2. Light is a wave right? So why doesn't motion of the observer, towards approaching light waves, result in an increased observed frequency?

3. Вам не стыдно, что Вас электромагнитный эффект Физо заставляют называть акустическим эффектом Доплера? Это не одно и то же. Разберитесь в этом. Делается это специально. Это связано с фальшивыми математическими теориями Эйнштейна и, естественно, со всей релятивистской физикой.

4. I have been through all of youtube and found this.
   This is the best explanation of the Doppler Effect.

5. Wow!

6. We call this lamda prime. Why? Because this is what Newton is going to hear when he gets run over. lol!

   I've been searching for an explanation of the frequency shift due to a moving source, and every video I've watched pretty much says that it just does. Your explanation makes is both very clear and understandable. Brilliant!

   Thanks for sharing your knowledge.

7. Thanks a lot!

8. you are great

9. Is the kid okay?

10. This guy makes me laugh out loud. Enjoy

11. 3 people who disliked will never get doppler's effect…

12. nice presentation in general. recommendable for many reasons.One minor point…….when you say the frequency the guy on the pier sees, and the frequency he sees when he is in his boat…. well, i think it would be better to say … the frequency he feels on his feet or how he feels the boat bobbing up and down. This is much more definite than his visual experiences which are rich and varied… for example… the guy in the boat still SEES the little boy in his ring bobbing up and down with the same original frequency!! (classically).You need to specify we are interested in what frequency the man sees locally or better what he experiences locally. For example it could even be totally foggy and he still experiences the oscillating surface. That pinpoints what we are talking about.

13. Was that example inspired by when you sat on a pier deciding whether to wet your feet and go rescue a kid screaming in the sea and you decided to do it but went back because of a Snicker pang?

14. Why its speed should be added when the listener moving toward the source ?

15. "The wavelength is measured the same by everybody."

    The same wavelength for both a stationary observer and one moving towards a LIGHT source? Be careful – your Divine Albert is in trouble. You could try to save him by explaining how the motion of the observer changes the wavelength of the incoming light so that the speed of the waves relative to the observer gloriously remains constant.

16. Thank you so much!! listening to different ways of approaching the same topic helps me alot at understanding! cheers 

17. Good sir, I tippeth mine hat to you 🙂 You taught me more in nine minutes than my professor did in an entire week.

18. One of my friends called you the Sal Khan of real paper 😀

19. man I SAW your face in one of your vids…lol you definitly dont look like what you sound. ANYWAY THANKS FOR THE HELP BOTHA

20. Wow, so at the end, we practically hear nothing whatsoever if we move at the same speed as the emitting wave speed. That's like how we stay in a moving vehicle we hear nothing, but other people around us that are not moving can.

    I don't know but, that's just so.. I should stop and trapped myself in this amazement. 

21. Man you ROCK !! (thumbs up)

22. Correct in point 1 – we'd combine the effects of approaching observer and approaching source. Immediately after we pass the ambulance, though, we'd have to reverse the sign of u AND v in the equation. This would cause the apparent f to drop dramatically, and suddenly!
