Sound Waves and Applications

How do musical instruments produce sound waves?

• By creating magnetic waves

• By emitting light waves

• By absorbing water particles

• By vibrating air particles

What is the frequency range for human hearing?

• 30 Hz to 25,000 Hz

• 10 Hz to 15,000 Hz

• 5 Hz to 30,000 Hz

• 20 Hz to 20,000 Hz

Give an example of a high-pitched sound and a low-pitched sound.

• Flute and Tuba

• Whistle and Drum

• Bell and Thunder

• Scream and Guitar

Describe the process of sound production in a string instrument.

• The strings are set into vibration by plucking, bowing, or striking, creating sound waves that travel through the air.

• The strings produce sound by emitting light waves

• The sound is produced by tapping the instrument on a hard surface

• The strings are set into vibration by blowing air into them

What are the different ways in which sound waves can be used in technology?

• Transportation

• Cooking

• Weather forecasting

• Communication, medical imaging, sonar, and industrial applications
