Waves & Sound

The highest point on a wave is the

• wavelength

• crest

• trough

• amplitude

The lowest point on a wave is the

• crest

• frequency

• wavelength

• trough

The horizontal distance between crests

• amplitude

• frequency

• crest

• wavelength

A wave in which the vibration is in the same direction (parallel) as that in which the wave is traveling is a

• longitudinal wave

• ocean wave

• transverse wave

• mechanical wave

The part of a longitudinal wave where the particles of the medium are close together is called a

• rarefaction

• compression

• crest

• trough

A part in a longitudinal wave where the particles are spread apart is called a

• compression

• rarefaction

• crest

• trough

If a wave is traveling at 260 m/s and has a wavelength of 0.8 m/s, what is its frequency?

• 208 Hz
• 325 Hz
• 430 Hz
• 160 Hz

Sound is produced by:

• Heat energy

• Low temperatures

• Vibrations

• Friction

The speed of sound depends on these two things:

• What it is travelling through (medium) and the temperature of the medium

• Speed of the medium and temperature of the medium

• Temperature of the medium and sound of the medium

• None of the above

Sound waves travel the fastest through

• Liquids

• Gases

• Solids
