3/29/2009 1 Light has dual nature – particles and waves The particle nature of light was the basis for ray (geometric) optics The wave nature of light is needed to explain various phenomena Interference Diffraction Polarization Ch 24 Wave Optics 24.1 Conditions for Interference t +1 -1 t +1 -1 t +2 -2 + Constructive Interference In Phase t +1 -1 t +1 -1 t +2 -2 + Destructive Interference Out of Phase 24.1 Conditions for Interference For sustained interference between two sources of light to be observed, there are two conditions which must be met The sources must be coherent They must maintain a constant phase with respect to each other The waves must have identical wavelengths

3/29/2009 2 Thomas Young - 1801 The narrow slits, S 1 and S 2 act as sources of waves The waves emerging from the slits originate from the same wave and therefore are always in phase 24.2 Young’s Double Slit Experiment The pattern consists of a series of bright and dark parallel bands called fringes Constructive interference occurs where a bright fringe appears Destructive interference results in a dark fringe Interference Patterns Constructive interference occurs at the center point The two waves travel the same distance Therefore, they arrive in phase
