Waves, esp sound

What is a rapid back-and-forth motion that can occur in solids, liquids or gasses?

• vibration

• sound

• light

• rarefaction

A sound wave is a type of:

• longitudinal wave

• transverse wave

• mechanical wave

• mechanical and longitudinal wave

You usually hear sound through the medium of:

• air

• water

• fire

• earth

The pitch of a sound depends on its:

• frequency

• amplitude

• intensity

• loudness

The human ear can detect frequencies between:

• 20 and 20000 Hz

• 100 and 200 Hz

• 1 and 100 Hz

• 20 and 30 Hz

Frequency is measured in:

• decibels

• Hertz

• meters

• seconds

The correct unit for wavelength is:

• Hz

• S

• m

• cm

The distance between two troughs in a wave is:

• frequency

• wavelength

• equilibrium

• period

• Longitdinal Wave
• Transverse Wave

What type of wave is this?

• Longitudinal
• Transverse
