What property of waves does this illustrate?

• reflection

• refraction

• interference

• diffraction

• polarization

Answer explanation

when waves pass through a gap they spread out - this is called diffraction

Which properties of waves is this?

• refraction

• diffraction

• interference

• reflection

• rarefaction

Answer explanation

When the waves from two sources meet they interfere.
