Waves
All waves need a medium in order to travel
False its mechanical waves
In a transverse wave the matter in the medium moves back and forth in the same direction that the wave travels
False longitudial
Transverse and congressional waves are the two types of mechanical waves
False longitudinal and transverse
Waves transfer matter as they travel
False waves transfer energy as they travel
In a compressional wave,the denser the medium is at the compressions the smaller its amplitude
In a transverse wave,the higher the amplitude,the more energy it carries
The amount of time it takes for one cycle,or a complete wave motion that returns to its starting point is called the
Period
Anything that moves up and down or back and forth in a rhythmic way is vibrating
True
In a transverse wave,the peak of the wave is the crest and the lowest spot is the trough
True
The speed of a wave is determined by multiplying the wavelength by the frequency
True
As the frequency increases the period
decreases
The refraction of a wave is how many wave-lengths pass a fixed point each second
false it's frequency
In a compressional wave the matter in the medium moves back and forth at right angles to the direction that the wave travels
false transverse
All of the waves that require a medium to travel through
sound,and slinky waves
