Sound

What determines the pitch of a sound?

• From frequency

• From amplitude

• From sound volume

• From all three parameters

What changes does a person observe in sound with an increase in the frequency of oscillations in a sound wave?

• Pitch Boost

• Pitch Downgrade

• Volume up

• Volume down

In what environment do sound waves not propagate?

• In solids

• In liquids

• In the gases

• In a vacuum

When a sound wave passes from air to water, it changes...

• Frequency only

• Sound velocity only

• Sound frequency and wavelength

• Sound velocity and wavelength

Determine the wave length if the period of oscillation of the sound source is 0.005 s. The speed of sound in air is 330 m / s.
