Sound Waves Test Review

Front

What is amplitude in sound waves?

Back

Amplitude refers to the maximum extent of a vibration or oscillation, measured from the position of equilibrium. In sound waves, higher amplitude means louder sounds.

Front

How does amplitude affect the energy of a sound wave?

Back

As the amplitude of a sound wave increases, the energy of the wave also increases.

Front

What is the relationship between frequency and pitch?

Back

Frequency is the number of waves that pass a point in one second. Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.

Front

What is the difference between longitudinal and transverse waves?

Back

Longitudinal waves have oscillations in the same direction as the wave travels (e.g., sound waves), while transverse waves have oscillations perpendicular to the direction of wave travel (e.g., light waves).

Front

What causes sound waves to travel faster in water than in air?

Back

Sound waves travel faster in water than in air due to the closer proximity of water molecules, which allows for quicker transmission of sound energy.

Front

What is hearing loss and what are its common causes?

Back

Hearing loss is the partial or total inability to hear. Common causes include age-related deterioration of hair cells in the cochlea, exposure to loud noises, and ear infections.

Front

What is the role of the cochlea in hearing?

Back

The cochlea is a spiral-shaped organ in the inner ear that converts sound vibrations into electrical signals, which are then sent to the brain.

Front

What is the unit of measurement for sound intensity?

Back

The unit of measurement for sound intensity is the decibel (dB).

Front

What is resonance in the context of sound waves?

Back

Resonance occurs when an object vibrates at its natural frequency due to the influence of external sound waves, amplifying the sound.
