A disturbance that travels through a medium as a longitudinal wave

• sound
• wavelength
• pitch
• frequency

Which wave has the highest pitch?

• 1

• 2

• 3

• 4

The higher the frequency, the higher the pitch

• true

• false

How do these waves compare?

• all have the same wavelength
• all have the same frequency
• wave 3 has a longer wavelength than wave 4
• wave 2 has a higher frequency than wave 4

In materials in the same state of matter, sound travels more slowly in denser mediums.

• true

• false

Waves that move the particles of the medium in the same direction in which the waves are traveling (by compressing and expanding) are called...

• surface waves

• transverse waves

• combination waves
