Adjustable Single Slit

[M/L | t++ | —]
Diffraction pattern changes with slit aperture.

Airy's Disc

[L | t+ | —]
Circular aperture effect.

[In-Depth Description]

Rayleigh's Criterion

[L | t+ | ★★]
Variable width slit shows dependance of aperture size on resolution of two closely aligned lasers.

[In-Depth Description]

Telescope Resolution

[L | t++ | ★★★★]
An adjustable aperture in front of a telescope is closed down to show the Rayleigh limit.

[In-Depth Description]

Binary Star

[M | t+ | ★★]
Two small closely mounted bulbs simulate resolution problems.

[In-Depth Description]

Microscope Resolution

[M | t+ | ★★★]
1μm diameter latex spheres observed under a ×1000 magnification is limited by resolution.

[In-Depth Description]

Fresnel Diffraction

[L | t++ | —]
The optical limits of a microscope are demonstrated as one attempts to resolve 1 μm diameter spheres.
