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
