Sound Waves

Front

How is sound loudness measured?

Back

in decibels.

Front

Loudness (volume) is related to__________________ (this part of the wave).

Back

amplitude.

Front

The speed of sound is fastest in which of the following media: Plasma, Gas, Liquid, Solid?

Back

Solid.

Front

True or False: Dogs can detect sounds well over 20000 Hz.

Back

True.

Front

Pitch is related to____________________.

Back

frequency.

Front

What is the definition of sound wave?

Back

A sound wave is a longitudinal wave that is created by vibrating objects and propagated through a medium (solid, liquid, or gas).

Front

What is the relationship between frequency and pitch?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What unit is used to measure frequency?

Back

Hertz (Hz).

Front

What is the formula for calculating the speed of sound in air?

Back

Speed = 331.5 + (0.6 × temperature in °C) m/s.

Front

What is the difference between amplitude and intensity in sound waves?

Back

Amplitude refers to the maximum displacement of particles in a wave, while intensity refers to the power per unit area carried by the wave.
