Unit 7 Waves review

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

• amplitude

• crest

• trough

• wavelength

What property of the wave is represented by the letter "B"?

• 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

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

• frequency
• period
• longitudinal 
• transverse wave 

The type of waves that require medium to pass:

• Mechanical Waves
• Electromagnetic Waves

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.

Which wave in the diagram has the greatest frequency?

• 1
• 2
• 3
• 4

When a wave strikes and object and bounces off. (example echo)

• medium
• refraction
• reflection
• interference

The ___________________ of waves can change when the waves move from one medium to another.

• altitude
• amplitude
• speed
• compression
