Explore light interference in real time: Young's slits, diffraction grating, Lloyd's mirror, glass plate, with monochromatic or white light.
LabOptique is a virtual lab to explore and understand light interference, from high school to undergraduate physics.
Investigate many aspects of light interference: from the notion of path difference up to the effects of a glass plate and the concept of coherence length, in a variety of situations — Young's holes or slits (infinitely thin or wide), freely movable sources to recreate a Michelson setup, a diffraction grating, Lloyd's mirror, with a monochromatic source or in white light.
What you can explore:
• Young's holes and slits (thin or wide)
• Path difference and interference order
• Diffraction grating
• Lloyd's mirror (phase shift on reflection)
• Glass plate (refractive index, thickness)
• Coherence length and wave trains
• Monochromatic or white light (channeled spectrum)
• 3D view of the interference surfaces
Everything is interactive and real-time: move the sources and point M, watch the interference pattern, the signal and the spectrum.
