FLASHCARD QUESTION
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.
2.
FLASHCARD QUESTION
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.
3.
FLASHCARD QUESTION
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.
4.
FLASHCARD QUESTION
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.
5.
FLASHCARD QUESTION
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).
6.
FLASHCARD QUESTION
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.
7.
FLASHCARD QUESTION
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.
