DOPPLER EFFECT

Doppler Effect = change in pitch or frequency due to moving sound source or receiver


Super sonic breaking the sound barrier

Super Sonic & Breaking the Sound Barrier

Sonic boom is a noise similar to thunder caused by an object moving at supersonic speeds, faster than sound, about 750 mph.


Physics and math of sound

  • Any elastic material can transmit sound.

  • Echoes are reflections from smooth, hard surfaces.

  • Echo free rooms sound “dead.”


Calculating the speed of a wave remember speed is distance over time

Calculating the speed of a wave(remember  speed is distance over time)

V = lf

Hz

m/s

m

1/s


V l f

V = lf

  • A wave has a frequency of 4.05 hertz and a wavelength of 4.00m. What is the wave’s speed?

    f =4.05Hzl = 4.00m

    V = lf

    v = (4.00m)(4.05Hz)

    v = 16.2 m/s


V l f1

V = lf

  • = V

  • f

  • f= V

  • l


Physics and math of sound

Noah stands 170 meters away from a steep canyon wall. He shouts and hears the echo of his voice one second later. What is the speed of the wave?

Total distance = 170m+170m =340 m

Time = 1 s

v = d/t

v = /

v = 340 m/s

340 m

1 s
