Sound Waves Flashcards
What is a sound wave?
A sound wave is a longitudinal wave that transmits energy through vibrations in a medium.
True or False: Sound waves can travel through a vacuum.
False
What is the speed of sound in air at room temperature?
Approximately 343 meters per second
How does sound travel through solids compared to gases?
Sound travels faster through solids than through gases.
What is the unit of measurement for frequency of sound waves?
Hertz (Hz)
What is the relationship between frequency and pitch of a sound wave?
Higher frequency sound waves correspond to higher pitch.
What property of a sound wave determines its loudness?
Amplitude
What is the formula to calculate the speed of sound in a medium?
Speed of sound = frequency x wavelength
What is the range of frequencies that humans can generally hear?
20 Hz to 20,000 Hz
What is the phenomenon where sound waves reflect off surfaces?
Echo
What is the term for the change in frequency of a sound wave due to motion relative to the observer?
Doppler effect
What is the term for the bending of sound waves around obstacles?
Diffraction
What is the term for the interference of sound waves that results in increased amplitude?
Constructive interference
What is the term for the interference of sound waves that results in decreased amplitude?
Destructive interference
What is the process of converting sound waves into electrical signals for recording or transmission?
Transduction
What is the term for the frequency at which an object vibrates naturally?
Resonance
What is the term for the bending of sound waves due to changes in the speed of sound in different media?
Refraction
What is the term for the enhancement of sound waves by adding energy at specific frequencies?
Acoustic amplification
What is the term for the reduction of sound intensity as it travels through a medium?
Attenuation
What is the term for the phenomenon where sound waves are bent upward due to temperature inversion in the atmosphere?
Temperature inversion effect
What is the term for the reflection of sound waves off the ground, resulting in delayed arrival of sound?
Ground effect
What is the term for the cancellation of sound waves due to their interaction?
Acoustic interference
What is the term for the process of reducing unwanted noise in a sound signal?
Noise cancellation
What is the term for the study of sound waves and their behavior?
Acoustics
