Semester II Final

The number of wavelengths that pass a point each per second is:

• frequency
• period
• longitudinal 
• transverse wave 

The distance measured crest to crest, or trough to trough.

• crest

• trough

• amplitude

• wavelength

The units for frequency are measured in _____________.

• hertz
• seconds
• m/s
• grams

What kind of wave is pictured below?

• compressional wave

• transverse wave

• sound wave

• mechanical wave

A wave carries...?

• energy only
• matter only
• energy and matter
• neither

Through which of these media do sound waves travel the fastest?

• rock

• air

• seawater

• foam

Waves that require a medium are known as

• Hardcore waves

• Mechanical waves

• Air waves

• Heat waves

The material through which a wave travels is?

• a rope

• water wave

• space-time continuum

• medium

Review: What is it called when a wave bounces off an object?

• Reflection

• Refraction

• Diffraction

What is the definition of Refraction?

• The bending of waves as they enter a new medium

• When two interfering waves have a displacement in the opposite direction, crest and trough overlap. Zero amplitude.

• When two interfering waves have a displacement in the same direction, two crests and two troughs overlap. Increased amplitude.
