Wavelengths

Accepts temperature in Kelvin, pressure in millibar and wavelength in microns (accurate for wavelengths 0.20-4.00 microns) and returns the model atmosphere Rayleigh angular volume-scattering coefficient. Includes Chandrasekhar phase function. Platforms: Matlab

The speed of light is generally rounded down to 186,000 miles per second. In exact terms it is 299,792,458 m/s (meters per second - that is equal to 186, 287.49 miles per second). It takes 8 minutes 17 seconds for light to travel from the Sun's surface to the Earth. Red, green and blue are the... Platforms: Windows

This application allows you to study the factors involved in an experiment with a Fabry-Perot interferometer. It lets you visualize the result of the multiple-wave interferences produced in the interferometer cavity when an extended source emitting two extremely close wavelengths is used. In this...

The Young Two Slit Interference model simulates the interference pattern of light as it travels through two slits to a screen. This result was first described by Young who used the wave theory of light to describe the interference of light through two slits. The interference pattern is due to the... Platforms: Mac

The Stellar Blackbody Radiation Curves model simulates the blackbody radiation curve of stars and how this leads to the observed color and luminosity of the star. If a star can be treated as a blackbody, the blackbody radiation curve of the star, the power density per area (or intensity) per... Platforms: Mac

The Chandra X-ray Observatory is the worlds most sophisticatedX-ray telescope. Along with the Hubble Space Telescope and the Spitzer Space Telescope, Chandra is one of NASA's 'Great Observatories'. Chandras unique sensitivity and resolving power have made possible significant advances in many... Platforms: Mac

The award-winning periodic table of the elements for the Macintosh. In addition to the usual information found in such programs, The Atomic Mac also contains a wealth of nuclear information on each isotope, including half life, decay mode, and daughter products. No other periodic table of the... Platforms: Mac

A Fabry-Parot Filter consist of the cavity formed by two highly reflective mirrors placed parallel to each other , as shown in the figure 1.The input light beam to the filter enters the first mirror at right angles to its surface. The output of the filter is the light beam leaving the second... Platforms: Matlab

Only in very simple situations can we describe the correlation between two time series as a single number. Often it varies both as a function of time, and of wavelength. Datasets may be uncorrelated on short timescales due to noise, but strongly correlated on larger wavelengths (eg annual).This... Platforms: Matlab

MatPlanWDM is a network planning tool for wavelength-routing WDM networks. The input parameters to the planning problem are the network physical topology, the traffic matrix, and technological constraints like the number of transmitters, receivers, optical converters and wavelengths available. It... Platforms: Matlab

Set of functions providing the attenuation and energy absorption coefficients of x-ray and gamma-ray photons in various materials, based on NIST report 5632, by J. Hubbell and S.M. Seltzer.X = PhotonAttenuation(Material, Energy, Options, Thickness)Function providing the attenuation and energy... Platforms: Matlab
