Give a difference between Mechanical waves.

Identify a difference between longitudinal & transverse waves.

• Transverse has compressions & rarefactions
• Longitudinal has crests & troughs
• Waves on a rope are transverse
• Ocean waves are longitudinal

Waves transfer _______ but not ________.

• matter......energy
• energy.....matter
• speed.....particles
• particles.....speed

What is the major difference between EM & Mechanical waves?

• EM waves causes vibrations
• Mechanical waves transfer matter
• EM waves are all longitudinal waves
• Mechanical waves require a medium

A medium can be a type of:

• solid
• liquid
• gas
• all of the above

A pencil looks broken when placed in a glass of water because...

• light speeds up when it changes mediums
• light slows down when it changes mediums
• light is reflected when it changes mediums
• light is absorbed when it changes mediums

Due to Hurricane Matthew the waves height in the Charleston Harbor increased by 3 feet. Height is the same as...

• frequency
• speed
• amplitude
• wavelength

15 waves break at your feet while walking through the sand at Folly Beach. This is an example of the waves _________

• frequency
• amplitude
• speed
• wavelenght

Properly known as the distance from one trough to another

• frequency
• speed
• amplitude
• wavelength

How are frequency and wavelength related?

• Higher frequency = longer wavelength
• Lower frequency = shorter wavelength
• Higher frequency = shorter wavelength
• No relation

How does the amplitude of a sound wave affect what you hear?

• higher amplitude, less energy, quiet sound
• lower amplitude, more energy, louder sound
• higher amplitude, less energy, louder sound
• lower amplitude, less energy, quieter sound
