Interference, Reflection, and Diffraction

The video tutorial covers wave interference and diffraction, explaining how waves interact with each other and boundaries. It introduces the concept of superposition, where waves can occupy the same space, leading to interference patterns. Constructive interference results in increased amplitude, while destructive interference can cancel waves out. The tutorial also discusses periodic waves, phase alignment, and how waves reflect and diffract when encountering boundaries. These principles are crucial for understanding phenomena like noise cancellation and the development of quantum theory.

What is the term used when two waves occupy the same space and form a new pattern?

• Reflection

• Superposition

• Diffraction

• Refraction

What happens to the amplitude of waves during constructive interference?

• It becomes zero
