42. Reflection
Refraction
Reflectionis the change in direction of awavefrontat aninterface
Refractionis the change in direction of awavedue to a change in its speed.
Diffraction
Interference
Interferenceis the addition of two or morewavesthat results in a new wave pattern.
Diffraction isthe apparent bending of waves around small obstacles and the spreading out of waves past small openings.
