The wave reflects from the speeders car and returns to the, Ask an Expert

Academics

Multiple-Concept Example 6 reviews the concepts that play a role in this problem. A speeder is pulling directly away and increasing his distance from a police car that is moving at 22 m/s with respect to the ground. The radar gun in the police car emits an electromagnetic wave with a frequency of 7.8 x 109 Hz. The wave reflects from the speeder's car and returns to the police car, where its frequency is measured to be 280 Hz less than the emitted frequency. Find the speeder's speed with respect to the ground.
