how does diffraction work
it goes through water and air
is a wave stopping at a wall
a wave bounces off of light
is the bending of a wave as it passes around the edge of an object

When a compression interferes with another compression, what occurs?
They counteract and the wave stops.
They combine to create a larger compression.
They combine to create a rarefaction.
None of the above.
When a crest and a trough interfere, what occurs?
They combine to create a higher amplitude wave.
They counteract and the wave either lessens or stops completely.
