The Doppler effect (or Doppler shift), named after the Austrian physicist Christian Doppler, who proposed it in 1842 in Prague, is the change in frequency of a wave (or other periodic event) for an observer moving relative to its source. It is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from an observer. The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession.

The Agricultural Commissioner/Weights & Measures Department routinely conducts price verification inspections at retail locations to confirm that prices charged to consumers are the same as those posted or advertised. On a typical visit to a store, the inspector will select up to 15 items and then take them to the check stand for payment. When the items’ bar codes are scanned at the register, the price showing at the register must match what is posted on the shelf or advertised. If the prices do not match, the store will receive a notice of violation and the case may be turned over to the District Attorney’s Office or local city attorney for prosecution.
