Interference and Diffraction

Page
Newton's Rings [S | t++ | ★★★] Circular interference pattern formed between spherical and flat glass plates. [ In-Depth Description] Thin Film Interference [M | t+ | ★★★★] Interference patterns on soap films or oil slick. [ In-Depth Description] Gold...

Edge Diffraction

Presentation

What it shows:

A point light source will produce seemingly sharp shadows which turn out to be not at all sharp when viewed under magnification. Narrow interference bands are seen within the shadow of a straight edge while more complicated shapes yield...

Ripple Tank Wave Phenomena

Presentation

Interference patterns of water waves generated by different sources at adjustable frequency.

circular waves
ripples

What It Shows

Various wave phenomena demonstrated with water waves: circular waves from point sources, plane waves from an array of point sources, change of...

Rayleigh's Criterion

Presentation

What it shows:

The criterion for the resolution of two sources is that the central maximum of the single slit interference pattern of one source falls on the first minimum of the pattern of the second source.

How it works:

Each laser beam passing through...

Interference, Refraction & Diffraction

Electromagnetic Waves

Page
Faraday Rotation [M | t+ | ★★★] Light, passing through heavy glass, has its direction of polarization rotated slightly if a magnetic field is applied to the glass. [ In-Depth Description] Electromagnetic Spear [M | t | ★★] Three dimensional model showing...

Microwave Properties

Presentation

10 cm microwaves are used for the demonstration of travelling and standing waves, reflection, interference, refraction, diffraction, absorption, polarization, tunneling, and waveguides.

What it shows:

The following is a sequence of experiments that can...

Quantum Mechanics

Page
Black Body Radiation Lamp [M | t | ★ ] Tungsten filament lamp whose color is temperature dependant in accordance with Planck's radiation law. [ In-Depth Description] Wien's Displacement Law [L | t+ | ★★] Changes in the spectral intensity distribution of a...

Double Sound Source Interference

Presentation

What it shows:

Two loudspeakers, separated about 1.7 meters emit the same tone of frequency 500 Hz and produce a pattern of constructive and destructive interference.

How it works:

At this frequency, the successive positions of constructive interference...
