What is the term for the maximum displacement of the particles of the medium from their normal position?

Amplitude

Sound cannot travel in a ______.

Vacuum

True or False: Sound travels faster in gases than in solids.

False. Sound travels faster in solids than in gases.

How is frequency defined in the context of sound waves?

Frequency is the number of vibrations made by a particle of the medium in one second.

Riddle: I can be high or low, made by vibrations, and my speed depends on the medium. What am I?

Sound

Which unit is used to measure the loudness of sound?

Decibel (dB)

Fill in the blanks: The time taken by a particle of the medium to complete one vibration is called ______.

Time Period

What type of wave is sound classified as?

Longitudinal wave

True or False: The loudness of a sound does not depend on the amplitude of vibration.

False. The loudness of a sound depends on the amplitude of vibration.

What is the relationship between time period (T) and frequency (f)?

Frequency f = 1/T.

Riddle: I am produced by vibrating strings, my pitch changes with tension, and I am often found in orchestras. What am I?

Stringed instrument

How does the loudness of sound change with distance from the source?

The loudness decreases as the distance from the source increases.

Fill in the blanks: The distance between two consecutive compressions or two consecutive rarefactions is called ______.

Wavelength

Which characteristic of sound is determined by the amplitude of the wave?

Loudness

True or False: A higher frequency corresponds to a lower pitch.

False. A higher frequency corresponds to a higher pitch.

What does the term 'quality' or 'timbre' refer to in sound?

Quality refers to the characteristic that makes two sounds of the same pitch and loudness sound different.

Riddle: I am a sound with only one frequency, produced by a tuning fork. What am I?

Monotone

What happens to the loudness of sound if the amplitude of the wave doubles?

The loudness becomes four times greater.

Fill in the blanks: Sound produced by a vibrating membrane is typically found in ______ instruments.

Membrane

What is the effect on pitch when the tension of a string is increased?

The pitch becomes higher.

True or False: The pitch of a sound depends solely on the loudness.

False. The pitch of a sound depends on the frequency.

Which factor does not affect the loudness of sound?

Frequency

Riddle: I am a unit of measurement for sound intensity, often used to describe loudness. What am I?

Decibel (dB)

How is the pitch of sound produced in wind instruments like a flute or clarinet changed?

By changing the length of the vibrating air column.

Fill in the blanks: The sound of a crying baby is typically ______ than that of a crying adult.

Shriller

The time taken by a particle of the medium to complete one vibration is called ______.

Time Period

True or False: Sound can travel in a vacuum.

False. Sound cannot travel in a vacuum; it requires a medium like solids, liquids, or gases.
