Superposition and Interference
Superposition occurs when two or more waves pass through each other. When two or more waves superimpose, the amplitudes are added together. it creates constructive interference or destructive interference.
Interference Simulation
Newton Ring
Newton rings are caused by the interference of two reflections. Newton Rings are observed when light is reflected from a plano-convex lens of a long focal length placed in contact with a…

Diffraction Grating
The diffraction grating is a transparent plate with a very thin line on the surface. Light (photons) like to go in the same phase. In the same phase, constructive interference occurs. If…

Why does a CD reflect rainbow colors?
Adjust the wavelength of light to choose the color of light you want. If you adjust the angle of reflection correctly, the phases of the light may coincide. That angle is the…

Thin Film Interference
Interference patterns seen in thin films If a thin oil film is floating on the water, you will see a beautiful pattern appear on the oil film. This is because the two…

Young’s Double Slit
The spacing and position of the slits can be adjusted. Young’s Double Slit experiment is a phenomenon in which light passing through two slits creates a specific pattern. Each slit acts as…
