14.3 Superposition and Interference

• Constructive interference occurs when waves are in phase.


  True
• The superposition of waves is crucial for understanding phenomena like standing waves, interference patterns, and diffraction
• Match the type of interference with its definition:

  Constructive Interference ↔️ Crests and troughs align

  Destructive Interference ↔️ Crests and troughs do not align
• Destructive interference occurs when waves are out of phase.


  True
• What is the principle of superposition in wave theory?

  Wave displacements add together
• When does destructive interference occur?

  Waves are out of phase
• What is interference in wave theory?

  Wave overlap interaction
• Constructive interference results in a larger combined wave amplitude.

  True
• How do wave displacements combine in superposition?

  Their amplitudes add
• Constructive interference occurs when waves are in phase
• Arrange the steps to explain constructive interference:

  1️⃣ Two or more waves interact

  2️⃣ Crests and troughs align

  3️⃣ Waves are in phase

  4️⃣ Combined wave amplitude increases
• Constructive interference occurs when waves are in phase, resulting in a larger combined wave amplitude
• Under what condition does constructive interference occur?

  Waves are in phase
• What happens to the combined wave amplitude during destructive interference?

  It decreases or becomes zero
• Superposition is the principle that when waves interact, their displacements add
• What is the combined wave amplitude during constructive interference if two identical waves are in phase?

  Double the original
• What happens when two or more waves interact during interference?

  Their amplitudes combine
• Destructive interference occurs when waves are in phase

  False
• Constructive interference results in a combined wave with double the original amplitude
• Perfectly out of phase waves with the same frequency and amplitude result in zero amplitude during destructive interference


  True
• Match the type of interference with its condition:

  Constructive interference ↔️ Waves are in phase

  Destructive interference ↔️ Waves are out of phase
