Adjustable Single Slit
[M/L | t++ | —]
Diffraction pattern changes with slit aperture.
Airy's Disc
[L | t+ | —]
Circular aperture effect.
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.
