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
