Pitch Quiz 8 C

What type of wave is a sound wave?

• Electromagnetic wave

• Mechanical wave

• Longitudinal wave

• Transverse wave

What unit is used to measure frequency?

• Ampere

• Volt

• Hertz (Hz)

• Watt

What are the characteristics of high pitch sounds?

• Higher frequency, shorter wavelength, perceived as more acute or sharp

• Higher frequency, longer wavelength, perceived as dull or flat

• Lower frequency, shorter wavelength, perceived as more acute or sharp

• Lower frequency, longer wavelength, perceived as dull or flat

What are the characteristics of low pitch sounds?

• Lower frequency, longer wavelength, deeper tone

• Shorter wavelength, higher frequency, brighter tone

• Higher frequency, shorter wavelength, higher tone

• Faster speed, shorter wavelength, higher pitch

Explain the concept of sound waves.

• Sound waves do not carry energy

• Sound waves are longitudinal waves that propagate through a medium by compressing and expanding the molecules in the medium. These waves carry energy and can be characterized by their frequency, wavelength, and amplitude.

• Sound waves are only characterized by their amplitude

• Sound waves are transverse waves that propagate through a vacuum

Give an example of a low pitch sound.

• Chirp of a bird

• Rumble of thunder

• Squeak of a mouse

• Whistle of a tea kettle

How can frequency be measured in sound waves?

• By determining the wavelength of the sound wave

• By calculating the speed of sound in the medium

• By measuring the amplitude of the sound wave

• By counting the number of complete cycles of the wave that pass a point in a given amount of time.
