Sound Waves (12.7 - 12.10)

Front

What is Reflection in sound waves?

Back

Reflection is the bouncing back of sound waves when they hit a barrier, allowing us to hear echoes.

Front

What is Refraction in sound waves?

Back

Refraction is the bending of sound waves as they pass from one medium to another, changing speed and direction.

Front

What is Diffraction in sound waves?

Back

Diffraction is the spreading out of sound waves when they pass through a narrow opening or around obstacles.

Front

What is the Doppler Effect?

Back

The Doppler Effect is the change in frequency or wavelength of sound waves in relation to an observer moving relative to the source of the sound.

Front

What is Constructive Interference?

Back

Constructive Interference occurs when two waves combine to form a new wave with a larger amplitude.

Front

What is Destructive Interference?

Back

Destructive Interference occurs when two waves combine to form a new wave with a smaller amplitude.

Front

What is a Longitudinal Wave?

Back

A Longitudinal Wave is a type of wave where the particle displacement is parallel to the direction of wave propagation, such as sound waves.

Front

What is a Transverse Wave?

Back

A Transverse Wave is a type of wave where the particle displacement is perpendicular to the direction of wave propagation, such as light waves.

Front

What is Resonance?

Back

Resonance is the phenomenon that occurs when an object vibrates at its natural frequency due to an external force.

Front

What is Amplitude in sound waves?

Back

Amplitude is the maximum displacement of a wave from its rest position, related to the loudness of the sound.
