→About The Doppler Effect
: When the source and [[observer]] are moving towards one another the [[wavelength]] of the [[wave]] will appear squashed shorter and the [[frequency]] will be higher.
: The '''Doppler effect''' can be noticed when cars pass by at high [[speed]]. At the cars are moving towards the [[observer]] the [[sound]] will be higher [[pitch]]ed but the moment the car goes past the [[sound]] will suddenly be lower [[pitch]]ed.
: The '''Doppler effect''' can be seen in the [[Visible Light|visible light]] [[emit]]ted by [[object]]s moving at extremely high [[speed]]. [[Light]] from [[object]]s moving away form the [[observer]] will appear to be longer [[wavelength]] and is referred to as [[Red Shift]]ted]] while [[light]] from [[object]]s moving towards the [[observer]] will appear to be shorter [[wavelength]] and is referred to as [[Blue Shift]]ted.
