Sound Waves and Frequencies study guide

These flashcards cover key concepts related to sound waves, frequency, resonance, and wave properties.

Speed of Sound in Air

343 m/s

Frequency Formula

f = 1/period

Wavelength Formula

λ = v/f

Resonance in Closed Tubes

The length of the tube is one quarter of the wavelength.

Tuning Fork Frequency

The frequency of the tuning fork affects the length of the tube required for resonance.

Standing Waves in Strings

A fixed string can create multiple resonant modes based on its length and tension.

Beat Frequency

The frequency of beats produced by two overlapping waves, calculated as the difference in frequencies.

Doppler Effect

The change in frequency or wavelength of a wave in relation to an observer moving relative to the source of the waves.

Transverse Wave

A wave in which the motion of the medium is perpendicular to the direction of the wave.

Longitudinal Wave

A wave in which the motion of the medium is parallel to the direction of the wave.

Node

A point on a standing wave that remains stationary.

Antinode

The points on a standing wave where the amplitude is at a maximum.

Fundamental Frequency

The lowest frequency produced by any vibrating object.

Harmonics

Whole number multiples of the fundamental frequency.

Wave Speed

The speed at which a wave travels through a medium.

Wavelength

The distance between consecutive points of similar phase in a wave.
