wave interactions ck12

false

only sound waves can be reflected

true

refraction occurs because waves change speed in a new medium

refraction

occurs because the wave starts traveling at a different speed in the new medium

diffraction

occurs when waves spread out and travel around obstacles or through openings in obstacles

reflection

an echo is an example of

refraction

is the bending of waves when they enter a new medium at an angle

reflection

is the bouncing back of waves from a surface that they cannot pass through

reflection, refraction, diffraction

types os was interactions include

size and wavelength

wave diffraction depends on

medium

wave interactions occur when waves pass from one type of material to another. These different materials are known as the of the wave

medium

wave interactions refer to interaction between a wave and its

They are reflected back at the same angle but at a different direction

what happens if waves strike a reflective surface at an angle other than 90 degrees
