Particles and Waves - Interference Flashcards
What does interference provide evidence for?
The wave model of light
What do coherent waves have?
A constant phase relationship and the same frequency
What are waves that coincide with peaks and troughs?
They are in phase
When does constructive interference occur?
When two waves with similar frequency coincide in phase
What are waves that coincide with peaks of one meeting troughs of the other?
They are out of phase
When does destructive interference occur?
When two waves coincide out of phase
When is a maxima produced?
When peak meets peak or trough meets trough
When is a minima produced?
When peak meets trough
When does diffraction occur?
When a wave passes an edge, when a wave passes through a narrow gap, or when a wave goes past objects
How can an interference pattern be producde?
In a double slit experiment
