The Doppler Effect definitions Flashcards

Change in frequency of sound due to relative motion between source and listener.

Number of sound waves passing a point per second, measured in Hertz (Hz).

Object emitting sound waves, such as a siren or speaker.

Person or device receiving sound waves from a source.

Speed of an object in a specific direction, crucial in Doppler calculations.

Constant speed at which sound waves travel, approximately 343 m/s in air.

Change in observed frequency due to motion of source or listener.

Movement of source and listener towards or away from each other.

Unit of frequency, representing one cycle per second.

Mathematical representation of the Doppler effect: FL = (v + vL) / (v + vS) * FS.

Convention in Doppler problems, from listener to source.

State of an object not in motion, affecting Doppler calculations.

Perceived frequency of a sound, higher when source approaches.

Disturbance that transfers energy through a medium, like sound.

Quantity with both magnitude and direction, such as velocity.
