Answer (1)
Answer:Here are the completed sentences:1. Waves are created when a source of energy causes a medium to vibrate.2. Waves that move the medium at right angles to the direction in which the waves are travelling are called transverse waves.3. What type of waves move the particles of the medium parallel to the direction that the waves are travelling? Longitudinal waves.4. The distance between two corresponding parts of a wave is its wavelength.5. The number of complete waves that pass a given point in a certain amount of time is called the wave's frequency.6. The unit used to measure frequency is Hertz.7. The lowest points of a transverse wave are called troughs.8. The highest parts of a transverse wave are called crests.9. A wave that can travel through an empty space is a light wave.10. If you increase the frequency of a wave, the wavelength must decrease.[tex].[/tex]
