  42. 42. Reflection<br />Refraction<br />Reflection is the change in direction of a wavefront at an interface <br />Refraction is the change in direction of a wave due to a change in its speed.<br />Diffraction<br />Interference<br />Interference is the addition of two or morewaves that results in a new wave pattern. <br />Diffraction is the apparent bending of waves around small obstacles and the spreading out of waves past small openings.<br />
