Waves

What property of this wave is represented by the letter "A"

• amplitude
• crest
• trough
• wavelength

The highest point on a wave is:

• the crest
• the trough
• the top
• the coast 

The lowest point on a wave is the:

• Amplitude
• Crest
• Trough
• Wavelength

When the frequency of a wave increases, what happens to the wavelength?

• The wavelength is not directly affected by the frequency of a wave.
• The wavelength increases.
• The wavelength decreases.
• More specific information is needed to form a conclusion about the wavelength.

A mechanical wave cannot travel through...

• a vacuum(empty space).
• water.
• air. 
• glass.

Which wave in the diagram has the greatest frequency?

• 1
• 2
• 3
• 4

Which wave in the diagram has the greatest wavelength?

• 1
• 2
• 3
• 4

regular disturbances that carry energy through matter or space

• crest
• energy
• wave
• trough

which material does sound travel the fastest?

• solid 
• liquid 
• gases

When a wave bends as it passes through at an angle from one medium to another.(example: pencil in a glass of water-)

• medium
• refraction
• reflection
• interference
