Energy Waves

What is the amplitude of a transverse wave?

• The energy that the wave carries
• The distance from the top of one crest to the top of the next crest
• The distance between the center of one compression and the center of the next compression
• The number of wavelengths that pass a given point in 1 second

Which of the following is NOT a characteristic of transverse waves?

• Low points are called troughs
• Energy causes matter to move in the same direction as the wave
• Has peaks and valleys at regular intervals
• High points are called crests

What is the frequency of a wave?

• The distance between the center of one compression and the center of the next compression
• The distance from the top of one crest to the top of the next crest
• The energy that the wave carries
• The number of wavelengths that pass a given point in 1 second

What is the difference between mechanical and electromagnetic waves?

• Mechanical waves require a medium to transfer energy, while electromagnetic waves do not
• Mechanical waves travel faster than electromagnetic waves
• Mechanical waves are transverse, while electromagnetic waves are compressional
• Mechanical waves are only found in outer space, while electromagnetic waves are found on Earth

Which of the following is NOT true about frequency and wavelength?

• Longer wavelengths result in smaller frequencies
• They are related for all waves that travel at the same speed
• They are measured in hertz
• Higher frequencies result in shorter wavelengths

Which type of wave can travel through outer space or a vacuum?

• Mechanical waves
• Electromagnetic waves
• Transverse waves
• Compressional waves

Which of the following is NOT true about sound waves?

• They are transverse waves
• They can travel through air, solids, and liquids
• They are mechanical waves
• They are compressional waves

What is the wavelength of a compressional wave?

• The energy that the wave carries
• The number of wavelengths that pass a given point in 1 second
• The distance from the top of one crest to the top of the next crest
• The distance between the center of one compression and the center of the next compression

Which of the following is NOT true about amplitude?

• It is related to the energy that the wave carries
• It is greater in compressional waves when particles are squeezed closer together
• It is greater in transverse waves when particles move in the same direction as the wave
• It is measured in hertz

What is the potential danger of high amplitude sound waves?

• They are produced by the motion of electrically charged particles
• They can travel through outer space
• They can be transverse or compressional
• They can cause damage to hearing
