Sound Waves 2023/2024

Sound is produced when something ______________

• Vibrates

• Moves through empty space

Answer explanation

Sound is produced when something vibrates, causing the air particles around it to vibrate and create sound waves. Therefore, the correct answer is 'Vibrates'.

High Amplitude =__________________

• Louder sounds

• Quieter Sounds

Answer explanation

High Amplitude corresponds to louder sounds, as it indicates a greater intensity or volume of the sound wave.

Low Amplitude = ______________

• Quieter Sounds

• Louder sounds

Answer explanation

Low amplitude refers to quieter sounds, as it indicates a lower intensity or volume level in the sound wave.

Low frequency = _______ Pitch

• Low

• High

Answer explanation

Low frequency corresponds to low pitch. The lower the frequency of a sound wave, the lower the pitch perceived by the human ear.

In General Sound waves travel the slowest in __________

• solid

• liquid

• Gas

• Plasma

Answer explanation

Sound waves travel the slowest in gas because the particles in gas are more spread out compared to solids and liquids, causing the sound waves to move slower through the medium.

In General Sound waves travel the fastest in __________

• solid

• liquid

• Gas

• plasma

Answer explanation

Sound waves travel the fastest in solids due to the close arrangement of particles allowing for quicker transmission of vibrations.

If the distance represented by the letter A (the amplitude) were increased, how would it change the sound?

• The sound would be higher. 

• The sound would be lower. 

• The sound would be softer. 

• The sound would be louder. 

Answer explanation

Increasing the distance represented by the amplitude (A) results in a louder sound, not a higher or lower pitch.

When a sound is louder what measurement gets bigger?

• Frequency 

• Amplitude 

• Wavelength 

• Crest

Answer explanation

When a sound is louder, the measurement that gets bigger is the Amplitude. Amplitude is the measure of the height of a wave, which corresponds to the loudness of a sound.
