An explanation of the doppler effectTHE DOPPLER EFFECTWhat is the Doppler effect?

From the centre of a stationary sound source.From a moving sound source- for example a fire truck.

Wavelength= distance between crests.

Longer wavelength, lower pitch.Smaller wavelength, higher pitch.The wavelengths are getting larger.

How was it discovered?

IMAGINE

Aha!Now to see If you have actually learnt what the Doppler effect is. There may be a prize for the winning group of 2/3Q1: WHERE DO THE SOUND WAVES BUNCH UP TOGETHER?Near the centre of the sound source.B. In the direction the sound source is travelling.C. Behind the sound source.

Q2:Who did a simpler test to prove that the Doppler effect existed?Alexander Ballot BuysB. Christoph Buys BallotC. J.C Doppler.Q3. When you have a higher frequency, you have a:Lower pitch B. Higher pitch

Q4. What year did J.C Doppler suggest the idea?1842B. 1857C. 1843LAST QUESTION.What was the name of the paper J.C Doppler wrote about the Doppler Effect?ber das farbiege Licht dan DoppelsterneB. ber das farbige Lichte der DappelstarneC. ber das farbige Licht der Doppelsterne BY JAMES + BEN ..
