Describe at least two ways that your understanding of the Doppler effect could be applied to everyday life

- - When I am driving very fast and I see a green traffic light ahead,

I need to be aware that the light could have been shifted toward shorter

apparent wavelengths because of my high speed approaching the source.

The light may actually be a red one, so I know that it would be wise to slow

down.

- - When I hear my wife yelling at me in a pitch that sounds higher than

her normal agitated voice, it's logical to assume that she is approaching

me at a high rate of speed, and I had better hide for my own good.
