Both energy & matter have different properties, including the way they travel and interact with their surroundings.
Concept #1: Understanding Refraction
In refraction, a particle changes direction as it moves from one medium to another. Energy (light) and matter refract differently.
Concept #2: Understanding Diffraction
In diffraction, a particle bends around an object it encounters. Energy (light) and matter will experience this phenomenon differently.
Concept #3: Understanding the difference between Constructive and Destructive Interference
In constructive interference, waves that are in phase will combine together and increase the amplitude. In destructive interference, waves are out of phase and cancel one another out.
