What is the term that describes the number of waves that move though a given point over time
In which type of waves do the particles in a medium vibrate in the same direction the wave is moving
Which characteristic of a wave describes the greatest distance a wave vibrates from a resting position
What is the term for the small packets of energy emitted from light
Which term describes substances that absorb some wavelengths of light
Which type of waves are combination waves that occur at the boundary between two media
Which of these waves would you expect to have the greatest wave speed

Which of the following is true of sound waves
sound waves require a medium to transfer energy
FOR A+ USERS THE ANSWER IS Sound waves travel in all directions
sound waves require a medium to transfer energy
-- They are longitudinal waves and material medium is required for their propagation.
What causes refraction-
Refraction is caused by light crossing from one medium to
another.
What occurs when two or more waves occupy the same space at the same time-
When two or more waves occupy the same space at the same time,
an interference pattern is created.
