The speed of light in a vacuum is 300,000,000 meters per second. What type of waves does light travel as?
vibration
sound
longitudinal
transverse
Which of the following statements is correct, based on the data in the table below?
Sound waves travel fastest through gases because there is more space between particles for the waves.
Sound waves travel fastest through liquids because they are denser than gases but not as rigid as solids.
Sound waves travel fastest through solids because of the density and organization of the particles.
The speed of sound waves is not affected by different states of matter.
When the particles of a medium are vibrating at right angles (perpendicular) to the direction of wave, then the wave is a ____ wave.
longitudinal
sound
standing
transverse
