The highest point on a wave is:

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

The lowest point on a wave is the:

• Amplitude

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.
