Interferences

This page delves into the concept of interference, a crucial phénomène ondulatoire exemple in wave physics.

Definition: Interference occurs when two waves of the same frequency interact. There are two types: constructive interference (in phase) and destructive interference (out of phase).

Key points covered include:

• Conditions for constructive and destructive interference
• Path difference (δ) and its significance
• Young's double-slit experiment

Vocabulary: The path difference (δ) is the difference between the distances traveled by two waves from synchronous sources that interfere at a point M.

Formula: For Young's double-slit experiment, the path difference is given by δ = (bx)/D, where b is the distance between slits, x is the position on the screen, and D is the distance to the screen.

Highlight: The interference fringe spacing (i) is the distance between two consecutive fringes of the same nature (bright or dark).
