Energy & Matter

Both energy & matter have different properties, including the way they travel and interact with their surroundings. 

Refraction vs. Diffraction

In refraction, a particle changes direction as it moves from one medium to another. Energy (light) and matter refract differently. 

In diffraction, a particle bends around an object it encounters. Energy (light) and matter will experience this phenomenon differently. 

Constructive Interference & Destructive Interference

Concept: 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.
