A longitudinal wave has a large amplitude if

• the crests are far apart.

• the compressions are dense.

• there are no rarefactions.

• the troughs are very low.

Speed, frequency, and wavelength are related by all of the following formulas except

• Frequency = Wavelength / Speed.

• Frequency = Speed / Wavelength.

• Wavelength × Frequency = Speed.

• Wavelength = Speed / Frequency.

Constructive interference occurs when two waves

• change their speed and bend.

• combine to make a wave with a smaller amplitude.

• combine to make a wave with a larger amplitude.

• are traveling in the same direction.

Scientists can tell how far away from them an earthquake occurred by

• the speed of S waves.

• the wavelength of P waves.

• the amplitude of surface waves.

• the time between the arrival of P waves and the arrival of S waves.

Waves that require a medium to travel through are called________________________ waves.

• maintenance

• motion

• mechanical

• modern
